Nomenclature and Descriptions of Ground Radar Types and Stations


Theses details as taken from, AMCO 31/1945 (AM File CS 12796/DDR 2, dated 21 April 1945)

When referring to a particular AMES the letter ‘T’ after the type number denotes a mobile equipment using trailers.

The letter ‘M’ similarly used indicated fully mobile equipment, all vehic1e being prime movers.

The omission of a suff1x indicates that the station is static or transportable - static indicating fixed buildings, and transportable semi-permanent buildings or tents.

Suffix ' AT " denotes station is air transportable.

In connection with Centimetric Air and Surface Watching stations it is intended to use blocks of AMES type numbers to indicate power as follows: -

30-39   Low power.

40-49   Medium power

50-59   High power.

As far as possible the unit figure will indicate a common type of equipment using different power transmitters. This scheme cannot be universal as odd types have to be included. These are indicated by the unit 1.

Types in common categories are: -

0          Basic Admiralty static shore station.

2          Basic Air Ministry static station, employing Nissen hut straddled by (CH/CHL gantry.

3          Equipment housed in existing CD/CHL or similar building

4          War (Office design steel tower 200 feet high with Nissen huts.

5          Air Ministry design on cantilever 200 feet high of CH steel tower with Nissen hut.

6          Air Ministry design wooden towers with Nissen hut.

7          Trailer set

S          Prime mover set, Admiralty design.

Function — in order to indicate the function it is proposed to use the following prefixes

A         Air reporting. 

S          Surface watching.      

C-S      Continuing Sweep,     dual     role air reporting and surface watching.

S-B      Stand-by (commonly for surface watching).
