In this paper, we investigate spectrally adaptive radar transmit waveform design and its effects on an active communication system. We specifically look at waveform design for point targets. The transmit waveform is optimized by accounting for the modulation spectrum of the communication system while trying to efficiently use the remaining spectrum. With the use of spectrally-matched radar waveform, we show that the SER detection performance of the communication system is minimally affected compared to the SER performance with a classical non-adaptive pulsed radar waveform. Moreover, we show the detection performance of the adaptive waveform is less impacted by the active communication compared to that of the pulsed radar waveform design. In other words the radar is able to coexist with a friendly communication system and thus share the spectrum with a friendly communication system.
