摘　　要：根据机载雷达标校的基本原理,提出了基于声体波延迟线的某型机载雷达距离方位误差的地面静态有源校准方法。标校时,机载雷达的工作状态与正常使用时一致,能够保证实际使用时的精度;另外,可以自动实现频率对准,不受机载雷达频率漂移的影响。分析了标校系统的性能,并且通过实验验证其实用性。Based on the fundmental principle of airborne radar calibration , this paper puts forward a new static active method to calibrate range and angle errors of an airborne radar with Bulk Acoustic Wave （BAW） located on ground. The work state of the airborne radar is consistent to the natural order while calibration, so the practical precision will be assured. The frequency will not be affected by the frequency excursion of the airborne radar because it is self-adjusted. Then the capability of the calibration system which has been tested in practice is described.
