The analysis of influence factors of chaff's jamming property in the rainy day

Chaff jamming is an important measure of antiradar, the paper carried out analysis of chaff's jamming efficiency based on the rainy day. Used chaff cloud's influence on radar wave attenuation in different rainfall rate to make mathematical models, and have done some research on chaff's jamming efficiency in different radar frequency. The result showed that the rain will enhance the effect of chaff jamming in different degree, which can offer a good reference value to the battlefield use of chaff.
