Spectrum sharing between radar and communications systems is currently under investigation because of the high demand for new wireless services and shortage of available bandwidth. To effectively design their coexistence, it is crucial to understand how current unaltered radar and communication systems would affect one another. This paper investigates the effect of radar interference on an uncoded data communication system where the optimal Maximum-A-Posteriori decoder is used and where the bandwidth of the radar system is much larger than the one of the communication system. Conclusions depend on how the radar interference power, measured by the Interferenceto-Noise ratio (INR), compares with the intended signal power, measured by the Signal-to-Noise ratio (SNR). For the case of real-valued modulation schemes, three regimes emerge: (a) Treat interference as Gaussian noise: when INR
