ABSTRACT:
Method and apparatus for enabling a pulse echo radar to generate a false signal in both time and frequency based passive Doppler ESM location systems. The latter false signal causes the ESM system to mislocate the radar. The radar's reference oscillator frequency is varied to create false passive Doppler information at an intercept receiver. These variations are predetermined changes in RF and PRF frequencies for the radar and are relatively small compared to those frequencies.
