A radar system (10) uses independent, adaptive modulation controls for the local oscillators (16, 40) in the transmitter (24) and receiver (26) portions. The adaptive modulation enables the radar to filter out any repeater jammer signal while maintaining a good signal-to-noise ratio (SNR) on the target. The radar system (10) provides a SNR that is sensitive to the target range and minimizes the SNR at the jammer range and maximizes the SNR at the target range. A communication system (60) similarly uses independent, adaptive modulation controls (66, 84) to provide a communication system resistant to jamming.
