内场RCS测试环境中误差的消减方法研究
Investigation on Reducing Environment Errors in Indoor RCS Measurement
摘要
Abstract
Measuring radar cross section (RCS) of target is very important for radar target recognition and radar imaging. Based on the principle of RCS measurement, the mechanism of errors generating from the ground is mainly discussed, the coupling of transmitting and receiving antennas, and the multi-path reflections from ceiling and walls are studied. An error-lessening method is put forward that is setting isolation absorbing screen between the testing port and turntable to remove the echo from the ground. Some absorbed materials are laid between transmitting antenna and receiving antenna and time domain counteraction to avoid antenna coupling. A time-gating function is adoped to eliminate the multi-path reflection from ceiling and walls. Through measuring the RCS of sphere, the interference from testing environment can be reduced by 1. 5 dB via getting rid of error produced by surroundings.关键词
