Research of Simulation Algorithm from Microwave Automatic Cancellation in Radar Life Detecting System / 医疗卫生装备

ABSTRACT

Objective To solve the signal interference problem by simulation algorithm when clutter signal can bring interference to radar life detecting system and reduce accuracy of its detecting. Methods According to some theory, automatic cancellation model was built up in computer with Matlab software. Results Simulation experiment shows that the cancellation composed signal So(t) is not correlative with the time and precision of auto-counteract but the amplitude and phase of clutter signal. Conclusion The results of the experiment have instructive significance about design of auto-counteract circuit.
