from Barry Davidson, photo dated 1947.
Barry Davidson provided the photo – more info would be great. It looks a bit like so called light warning radars but with a more sophisticated aerial. If it is a light warning radar it would be one of the 11 marks of the AMES 6 radar.
Barry has now found this second Changi picture, described “RAF Changi 1953 ATC Radar Trucks”. The trucks are RAF. The tripod on the left seems to have a powered rotator and may be the same mechanism as is concealed in the canvas shelter in the photo above. The CMP pattern truck on the right seems to be fitted with aerials and the open sides suggest maybe a generator or transmitter truck. There is another similar truck parked at right angles behind the first and two or three trucks or trailers with metal or wood (rather than canvas) backs – ops room, workshops etc? The vehicle on the left seems to have a roof rack to store aerial poles, masts etc.
