摘要
讨论了脉冲追赶空间同步方式下工作的双基地雷达的自适应波束形成技术．针对双基地雷达实验站，研制了基于数字信号处理实现的Ｇ－Ｓ正交算法的自适应数字波束形成设备．外场实验结果显示，在单个有源噪声干扰条件下，脉冲追赶式自适应数字波束形成对信干比具有１０ ｄＢ左右的改善，天线方向图在干扰方向上可形成－ ４０ ｄＢ以上的零点．
An Adaptive Digital Beam Forming realization technique for bistatic radars working in pulse chasing space synchronization mode are discussed. An ADBF experimental module base on DSP has been developed for an experimental bistatic radars station. Test results show that with this system, an improvement factor of 10 dB in signal to interference ratio can be obtained for jamming by a single active noise and a null of -40 dB can be formed in the antenna direction pattern.
