中文摘要：
介绍了非合作双基地雷达的基本几何关系,讨论了非合作双基地雷达中4个重要参数（基线距离、双基地距离差、发射站目标方位角、接收站目标方位角）的测量方法,利用这4个参数可构成4种测距算法。在考虑基线距离误差的情况下,推导了这4种算法的测距误差公式。仿真结果表明,各算法测距精度与双基地雷达的几何结构有关,通过优化可得空间测距精度最高区域。实际系统的测距方案应根据所能测出的参数进行选择,同时应注意各算法的适用区域。
英文摘要：
The basic geometrical relationship of non-cooperative bistatic radar is introduced, and the measuring methods of four parameters （baseline distance, bistatic distance difference, transmitter look angle and receiver look angle）, which can compose four distance measuring methods, are discussed. In the condition of considering the error of baseline distance, the error expressions of four distance measuring methods are deduced. The simulation results show that the distance measuring accuracy of each method is relative to the geometrical position of bistatic radar, and the district of highest distance measuring accuracy in space can be achieved by optimization. In practical systems, the selection of distance measuring method should depend on the parameters which can be measured, and the applicable region of each method should be taken in consideration.
