%X One of the major problems in continuous wave bistatic radar is direct-path interference. Conventional solutions to this problem is the use of an adaptive antenna, steering null towards the interference. Unfortunately the null depth obtained by this technology is not enough for surveillance radar. First of all, direct-path interference appeared in bistatic radar based on FM broadcast transmitter is analyzed in the paper; Secondly, a solution based on adaptive fractional delay estimation is introduced how to deal with this problem; Finally, a bistatic radar experimental system based on FM broadcast transmitter is discussed. Simulation results with real collected data show applying the method has better the performance of target detection.
