Radar sensors are common devices in daily traffic, especially for driver assistance and automotive safety systems. A high sensor density increases the probability of interferences, especially when the sensors occupy a large radar bandwidth. Many current sensors, e.g. chirp sequence radars, rely on frequency modulation schemes. A promising future radar concept applies orthogonal frequency division multiplexing (OFDM). This paper investigates the interference effect of an OFDM radar on a chirp sequence radar. Potential interference levels are derived and the influence of modulation parameters is evaluated with simulations.
