Outline CV

 

Education

 

Born :- 1936 at Cornerways, Kingsley Road, Hutton.

 

Went to Hutton C of E School in the village in 1941, where both his Father and Grandfather were educated

Passed 11 Plus Examination for entrance to Brentwood School in 1947.

Attended this School until 1952, then left to Join The Marconi Wireless Telegraph Company in Chelmsford as an Apprentice.

Attended Chelmsford Technical College in order to qualify as an Electrical/Electronic Engineer. Finally became a full Member of the IEE and Chartered Engineer in 1970.


Interests


Interests included hill walking and some simple rock climbing in Wales, Scotland, The Lake District and Austria.  Played semi-professional Jazz in many venues  from 1956, two, three or sometimes four nights a week. Main band was the Washboard Syncopators of which there are two recordings.

Rebuilt many motorcycles and cars. Specialised for some years in restoring Classic Motorcycles, but from about 1975 concentrated on modern high powered machines.

In 2002 still have a 1952 Vincent 500 which was bought in 1956 and is driven each year to the Isle of Man for demonstration runs round the TT course during Manx Grand Prix week. Also have a 750 cc Honda which is used to go to Air shows, vintage car events and to the Isle of Man TT Races in June.

Build and fly radio-controlled model gliders and powered aeroplanes and have also flown full sized gliders and light aircraft, but not to the extent of having a licence to fly solo.


Family


Married :- Jane Withers in 1968 who he met at a party in London. Her Father owned a small iron foundry in Mansfield Notts, which was closed down in about 1970.

Bought a house in Little Baddow and had two children - Anna in 1971 and Jonathan in 1973.

Anna now has a Doctorate in Geology and works in London as a specialist consultant on Sedimentology to British Petroleum. Jonathan follows the family tradition and is Agricultural Engineering Service Manager for E.Doe at Ulting.

Systems Section leader for TORH Project, based on Locus Computers.
The System provided intercept, auto tracking, 6x radar inputs, totes, and a touch MMI.
Many trips were made to Sweden during this Project.


Systems Engineering Yugoslavian BACCUS Project 1984-88

Systems Manager for the design of 2 x ADOCs and 4 x SOCs, with Multi-Head Tracking, Intercept, SAM, Flight Plan Input, G/A Data Links etc. on fixed sites.


Systems Engineering Display Group 1988-89

Worked on several D&DH Bids, mainly updates for the London Air Traffic Control Centre. Then worked on the Malaysian KAWAL Bid which provided my next big project.


Systems Engineering Malaysian KAWAL Project 1990-95

Requirement Authority for D&DH parts of system, comprising Display Shelters each with 4 x Consoles, Integration with Hughes System, Executive Operations Shelter, Training School and Software Bureau. Visited America and Malaysia several times for meetings and acceptance testing.


OSCR over the Horizon Sea Current Radar 1996

Helping to test this system during the Winter, out on the Essex Coast.


Sensors for SWMLU at Basildon 1996

Writing requirement specifications for Seawolf Mid Life Update Electro-Optic Systems


NATO SOC Replacement Bid

In Paris for three months to work with an international bid for a multi million pound contract.


JORN OTH Radar Fault Reporting Requirements 1997

Writing notes to clarify software processing for Australian over the Horizon Radar.

Thoughts on Pottery Lane and Great Baddow in the 1950s

 

(by Alan Matthews)

 

Thinking about when I joined the Radar Development Group at Broomfield, I realised that there was a “them and us” divide when I went to Broomfield in 1955, "them" being the Military Development Group at Baddow.
Basically Broomfield did the Private Venture (PV) designs and Baddow the work for the Ministry – presumably cost plus.
In 1959 the TV design lab moved from Baddow to Pottery Lane and the Broomfield display group moved to their old lab at Baddow, and some to rooms A123/124, while the High Power Radar group went to a lab under the tower.

 

Baddow


They had just about completed the Rotor display equipment design for the British Defence system which involved the Type 64 Consoles with their several racks of analogue equipment.


A set of equipment had been built in room 123 (I think) at Baddow for sorting out bugs and polishing maintenance procedures and was later used for the design of the Swedish Fur Hat display system, which used Marconi Private Venture displays instead of the Type 64 Consoles. I did a lot of work on this around 1961/62 under the guidance of Cliff Clarke to make it suitable for Sweden.


The Ministry design team comprised some extremely clever and highly-qualified engineers and scientists, with the general requirement to keep within 0.1% tolerance for most parameters – sawtooth deflection linearity, etc. These tolerances were maintained with valve equipment despite valves ageing, temperature changes, etc. and used very elegant circuit designs with chopper stabilisation and feedback.
I did not work on any of this design but was most impressed with their skills when I worked with them later in 1959 at Baddow.


Here are some of the Baddow team that I remember:


Roy Simons               64 Console
David Chandler          Analogue circuit design including timebases
Arthur Young             Rotation synchro servos and probably other designs
Derek Watkins           The co-ordinate resolver which produced the fixed coil system timebases
Tom Patterson
Len Wittaker


No doubt Roy Simons would have known many others.

 

Broomfield

 

The Broomfield display system under Peter Max had a completely different design team, though they were meeting a very similar design requirement to the Baddow Group and I never understood why the Ministry design from Baddow was not used as a basis. Perhaps there were security matters or design rights problems. Again I am sure Roy Simons will know.
I worked in a small team on the display equipment and height extraction for the S244 "Big Noddy" S-band heightfinder.


The team under Fred Kime comprised:


John Sellars               Project leader, display system designer
Norman Morton          Display circuit designer with John Sellars
Nick Tovey                 Interfaces between PPI displays and heightfinder control
Alan Matthews (Self)   Design of panel converter which turned the horizontal position of a display marker controlled by a Joystick into height numbers for distribution to height-requesting PPI display operators. This was designed to be 0.1% accurate and was really an early form of digital voltmeter.

Also at Broomfield on display systems with Fred Kime were:


Ken Knight        Display system team leader
Mike Boyaval     Display systems and rate aiding
Trevor Sawyer   Display backup circuits
Jack Cox           Display Backup circuits
Pat Daley          Range marks Generators
Tom Gaskell      Display Systems
Frank Burrows   Power Supplies
Derek Jeffries    Expert circuit designer
Don Beckett      Expert circuit designer


Many of these systems were sold to NATO, and some to Singapore, and South Africa
In 1959 this group went to Baddow and they were eventually integrated with the Baddow design engineers.


The High-Power Group at Broomfield

 

This group designed the High Power transmitters SR1000 SR1030 and signal processors and were in the high power lab under the tower.


H N C Ellis Robinson          Transmitter Group Chief
Bruce Neale                     Transmitter development Manager
Colin Latham                    Development Manager
Arthur Stevens                Waveguide systems
Fred Chittenden               Mechanical designer.
Dick Greenwood               Receivers and IF strips.
Eric Gildersleve                Radar Performance
Tony Slocome                  Signal Processing
Peter Barlow
Frank Henchie                  S244 Mechanical Designer
Pete Smith                       Mechanical Engineer – Did much work on the hydraulic Ram
George Tchaikovsky          S244 Servo Engineer.  He had terrible problems with the design

After this the display systems became Datamation, under Roger Shipway, designing the Fur Hat Swedish system and/or Linesman.
