However, one factor that often is overlooked when talking about jamming is radar cross section ( RCS ) of the target. When the range gate is sufficiently removed from the actual target, the deception jammer is turned off, forcing the tracking radar into a target reacquisition mode.
Some decoys can carry communication and jamming system allow them to perform cooperative blinking jamming with others decoys or aircraft to deal with HoJ missiles. Frequency-hopping: as the jammer need time to analyze signals and turn into it. Because the decoys (RF jammer) will be launched away from the launch aircraft, thus make Home on jam mode useless.
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.
Each source acts as a repeater-type jammer transmitting the same signal at the same time, and if the two signals arrive at the missile monopulse antenna approximately 180° out of phase, wavefront distortion occurs. I had a Detroit steel locker in the rear of my BJ70 Shortie (not recommended), you literally needed to re-learn how to drive and been full time, other road user’s were sometimes affected by my erratic driving.
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.
