Simulation research of microwave automatic clutter-cancellation in life-detection radar

Clutter signal can bring interference to life-detection radar and reduce accuracy of recognition. This research attempts to resolve the problem in clutter jamming by simulation experiment. The automatic clutter-cancellation model is established according to theories and experiments are simulated on computer. The result suggests that the variation of auto-cancellation signal is not correlative with time and precision of the cancellation but amplitude and phase of the clutter signal. The result has instructive significance for the design of digital auto-cancellation circuit in life-detection radar.
