摘　　要：针对传统雷达对抗侦察空域搜索效率不高的问题，提出一种优化搜索方法。该方法首先分析了利用二维阵列进行波束形成的原理；然后对固定目标的波位编排、搜索次序和驻留时间进行了研究，提出一种优化搜索方法；最后将上述方法推广到辐射源运动的情况，提出一种搜索区域动态更新方法。仿真实验表明，该方法能有效减少搜索时间，提高辐射源截获概率。Aimed at the problem that conventional airspace search method has a low effective- ness in radar EW reconnaissance, an optimized search method is proposed in this paper. First- ly, the principle of beam forming using two-dimensional array is analyzed. Then, the wave po- sition arrangement, search order and dwell time are studied, and an optimal search method is proposed. Finally, this method is extended to the case of radiation source movement, and a dy- namic updating method is proposed. Simulation results show that this method can effectively re- duce the search time and improve the probability of the radiation source.
