A waveform diversity technique for countering RGPO

In modern battlefield the jammer performing deception jamming of range gate pull off (RGPO) generates a false target and causes the radar to break its track on the target. The use of waveform diversity to remove the false target from the real one is considered. Received signal model under deception jamming is built on the base of the principle of RGPO. A new kind of design method for waveforms orthogonal in frequency domain is proposed and the correspondence signal processing method for removing the false target under RGPO is deduced. Its validity is proved by the simulated experimental results.
