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.
Support jamming signal is radiated from one platform and is used to protect other stand in jamming (SIJ) a remotely piloted vehicle is orbiting very close to the victim radar while transmitting jamming signalSince the jammer is closer to hostile radar , the power required to screen the same target of SIJ is much lower compared to SOJ.
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 …
