This application includes such applications as search and rescue, airborne early warning (AEW), ground mobile air defence, anti-submarine warfare (ASW), terrain following radar (TFR), maritime patrol aircraft (MPA).

TMD can supply tubes, amplifiers (tube & high voltage power supply) or more complete transmitters if required. We are currently working on the development of multi-tube transmitters to achieve optimum reliability & performance.
Case Studies/Testimonials
* Our of our S band transmitters used by a South American Navy vessel for general medium range surveillance is currently out-performing all other onboard radar and the customer was also very pleased with the service and support we gave them. "TMD's reaction was not only the best from the technical point of view, but also in time. So thank you very much, you have proved that it was the best decision to work with TMD".
* A particularly challenging surveillance radar specification was demanded by the power amplifier module (PAM) at the heart of the Sentinel radar - the US Army's premier ground based air defence radar. The ultra low phase noise requirement was eventually achieved by our power supply development engineers. Following delivery of the first PAMs the customer remarked "..the performance is so good we are dancing on the table!" This work won us a large order from the US Army and a Queen's Award for innovation in 2005. (see high voltage power supply section for more details). We had produced a radar power supply with a noise figure of better than -140 dBc/Hz CW equivalent single sideband random noise and better than -80 dBc spurious noise. Current state-of-the-art, prior to this innovation, was typically -100 to -120 dBc/Hz random - TMD had achieved an improvement of better than 20 dB or a factor of 100 times.
