By contrast ,for support jamming the closer the jammer to threat radar , the easier it would be for the jammer to cover others assets because in this case aircraft reflection is not depend on the distance between the jammer and the threat radar so getting the jammer closer to the radar is better.
Due to the bigger size, jamming pod often have bigger transmitting antenna and more power available compared to FOTD decoys and air-launched decoys, as a result, they have higher effective jamming power and better directivity ( gain ). At start, the jammer sends back an amplified version of the signal received from the radar.
In recent years capability of radar deceptive jamming has been enhanced significantly with the development of Digital Radio Frequency Memory (DRFM) techniquesJammers with DRFM technology are widely reported in literatureÂ , for example ALQ-187(v)2 ,Â ALQ-131 EA PUP , Falcon edge , …
The jamming signal must compete with the real target return to capture the radar angle tracker. The core of towed decoys is a transmitter that amplified and retransmits all signal it received thus it appears like an attractive target with high RCS on adversary radar.
In this type of jamming, all the power output of the jammer is spread over a bandwidth much wider than that of the radar signal. PRF jitters: a radar calculate range to a target by measuring the elapsed time between pulse transmittal and target return , the maximum required range of the radar determines the maximum pulse repetition frequency of the radar.
