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四个重要参数（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，利用这四个参数可构成四种定位算法。推导了这四种算法的定位误差公式。仿真结果表明，各算法的定位精度与双基地雷达系统的几何结构有关，且有着不同的空间分布规律。实际系统定位方案的选择应根据所能测出的参数来定，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 radars is introduced, and the measurement methods of four important parameters （baseline distance, bistatic distance difference, transmitter look angle and receiver look angle）, which can compose four kinds of location methods, are discussed. On the basis of them, the location equation and error expression of each method are deduced. The simulation results show that the location accuracy of each method is relative to the geometrical position of bistatic radar systems, and has different spatial distribution. In practical systems, the selection of location methods should depend on the parameters which can be measured, and the applicable region of each method should be noticed.
