An experimental FM radio based non-cooperative bistatic radar is briefly described,  and two related key techniques,  i. e. line-of-sight (LOS) signal cancellation and targets detection,  are listed in this paper.  Other than algorithms appeared in most papers,  NLMS based non-causal filters are used to equalize the array multi-channel differences.  The LOS signal about 80 dB above the noise level is cancelled completely after joint time-space processing.  Civil airplanes are detected 300 km away.  Experimental data verifies the simplicity and effectiveness of the proposed method.
