摘　　要：为了提高双基地机载雷达对指定区域的探测威力,提出了一种机载双基地雷达配置方式设计方法.在双基地机载雷达一发一收场景下,首先,根据双基最大探测威力确定接收机前出的距离;其次,根据目标处于发射和接收机的共视区确定双基的飞行高度,从而确定双基的位置;最后,建立机载双基地雷达杂波信号模型,根据杂波的分布特性和抑制效果确定双基的相对运动状态.仿真结果表明,所提方法能使机载双基地雷达达到要求的探测威力,并且使接收的杂波平稳性最高,从而为后续采用空时自适应处理技术抑制杂波提供条件.In order to enhance the detection capability of airborne bistatic radar over specified areas,a design method for the configuration of airborne bistatic radar systems is proposed.In the scenario of one-transmitter-one-receiver bistatic airborne radar,firstly,the forward placement distance of the receiver is determined according to the bistatic maximum detection range.Secondly,the flight height of both platforms is determined according to the target in the common coverage area of transmitter and receiver,so as to determine their spatial positions.Finally,a clutter signal model for airborne bistatic radar is established,and the relative motion state of both platforms is determined according to the clutter distribution characteristics and clutter suppression effect.Simulation results demonstrate that the proposed method can not only make the airborne bistatic radar reach the required detection range,but also make the received clutter stationarity the highest,thus providing conditions for the subsequent use of space-time adaptive processing technology to suppress clutter.
