摘　　要：双基地雷达受系统自身特点影响,其性能指标与单基地雷达有较大差异。本文结合某双基地LFMCW雷达系统,首先分析讨论了双基地雷达的测距精度,然后重点结合各种实际工程应用场景进行了计算机仿真。仿真结果表明,双基地雷达测距性能随收发两站布站方式及目标所处空间位置而变化。相关结论对双基地雷达的研制和性能评估具有重要指导意义。The performance index of bistatic radar differs with monostatie radar owing to its special geometrical configuration.Combined with a certain bistatic LFMCW radar system,the range accuracy of bistatie radar are analysed and discussed in this paper firstly,then computer simulation is carried out integrated with various cases of practical engineering application.It is indicated by simulation results that the range performance of bistatic radar is influenced by the station distribution and target spatial position.The conclusion may provide some insights into the design and performance evaluation for bistatic radar.
