Abstract: In this research, the critical implications of the phase response of a Digital Radio Frequency Memory (DRFM) based repeater system on the Doppler spectrum of a modern, coherently processing radar system (for example pulsed Doppler radar) are presented. It is shown that, in addition to the desired Doppler term due to the simulated movement of the repeated echo, the spectrum exhibits a number of unwanted terms which result in spurious responses in the processed radar data set. The radar could exploit these effects to identify the echo as a DRFM-based repeater jammer. When a DRFM is used in the testing of radar equipment the radar system performance will be incorrectly inferred. The paper concludes with a possible mitigation scheme
