Abstract :
It is a problem in passive radar that direct signal and multipath clutter is much stronger than the object echoes. Existing cancellation methods always impose that the arrival time of clutter is integer multiples of sampling period, which is impossible for real radar system. To solve the problem, a novel method of clutter cancellation using arrival time exactly estimation is proposed. Simulation results show the effectiveness of the new method.
