This application covers any sort of electrical or electronic device designed to confuse or distract radar, sonar, or other detection systems.
This can be broadly divided into Jamming in which the purpose is to transmit a signal which interferes with the performance of the enemy's radar or Decoy in which a signal is transmitted to confuse an incoming missile. This is usually achieved by a towed decoy on an aircraft or ship or alternatively by firing the transmitting decoy into the air or sea.
As with the radar market we have developed complex transmitter subsystems, CW, ICW or pulsed from 0.5 - 40 GHz, and have supplied many customised units worldwide - for naval, ground based and airborne ECM. Airborne applications are either on-board, pod mounted or towed (for decoys).
Many platforms require full MIL-SPEC products although for certain ground benign and naval sheltered applications our instrumentation amplifiers may be suitable (see later section).
Case Studies
*TMD has been active in the ECM market since 1990 and in 1994 we won a large power supply development contract for the towed decoy for Eurofighter which has resulted in successful on-going production contracts ever since.
* We supplied a high voltage power supply (the PTM6597) to the Indian radar manufacturer ASIEO for a range-gate pull off jamming system for a fast jet platform, which required a very short throughput delay (40 ns) for the power supply and TWT combined. The previous figure achieved had been 76 ns, so this was a very challenging development for TMD in which we succeeded. Eventually 7 units were delivered - of which one sample from the batch was subjected to full qualification testing for the harsh airborne environment.
"... other suppliers have to work very hard to match the performance and reliability of TMD's products".
