Abstract

Abstract:

In order to reveal the false target interference laws of dual frequency electromagnetic radiation to radar under the requirement of complex electromagnetic environment adaptability evaluation of equipment, the stepped frequency continuous wave radar is taken as the research object, based on the theoretical analysis and effect test, the waveform characteristics and location laws of false targets generated by radar under the interference of single frequency and dual frequency electromagnetic radiation are analyzed. The results show that, the single frequency electromagnetic radiation can make the tested radar produce a single "hill" false target, and its position is random. The dual frequency electromagnetic radiation can make the tested radar produce two "hill" false targets without intermodulation interference, and the positions of the two targets are random. However, the distance difference is related to the frequency difference of the dual frequency interference signal. The second order intermodulation interference signal can make the tested radar produce a single "spike" false target, whose position is related to the intermodulation frequency difference.

Key words: stepped frequency continuous wave radar, false target interference, dual frequency electromagnetic radiation, second order intermodulation
