摘要
在机载双基地协同探测雷达中,由于载机的阵位部署和平台运动,双基条件下的杂波特性比单基条件下的更复杂。本文分析了机载双基地雷达杂波空时分布特性,在传统机载雷达杂波模型的基础上,针对机载双基地雷达几何关系,考虑了双基地分置时接收波束和发射波束的相对关系等因素,给出更精确的机载双基地雷达杂波模型。对双机多种部署和姿态情况下的杂波空时分布特性和空时二维杂波谱进行了仿真,为机载双基地协同探测雷达杂波抑制的研究提供了技术支撑。
For airborne bistatic cooperative detection radar,owing to the deployment and movement of airborne radar platform,the characteristics of clutter for bistatic radar are more complicated than monostatic radar.The space-time distribution characteristics of airborne bistatic radar clutter is analyzed.Based on the traditional airborne radar clutter model,a more accurate airborne bistatic radar clutter model is given,aiming at the geometric relationship of airborne bistatic radar and considering the relationship of the receiving beam and transmitting beam.The space-time distribution characteristics and the space-time two-dimensional clutter spectrum of airborne bistatic radar clutter in different airborne deployment and attitude situations are simulated,which provides technical support for clutter suppression of the airborne bistatic cooperative detection radar.
