中文摘要：
二次雷达机制的协同式目标识别系统在军事中得到广泛应用。通过总结已有的协同式目标识别系统干扰和防御技术特点,对不同干扰样式下干扰距离和干扰功率间的关系进行研究,得出干扰样式选择与干扰距离、干扰功率的关系;对单脉冲测角和旁瓣抑制中使用的和差波束形成技术进行研究,提出一种零陷深、保形性好的基于自适应对角加载的波束形成算法用于形成和差波束。仿真表明,可以依据干扰距离选择合适的干扰样式;自适应对角加载算法能形成保形性好、零陷深的波束。
英文摘要：
The coordinate target recognition system based on secondary radar plays a great role in military. By summarizing interference and defense ways, a research is made for the relationships between jamming distance and jamming power of different jamming styles. In single pulse angle measuring and side lobe suppressing interference, sum and difference beamforming is used and a good beamforming method with deeper zero and keeping shape well is proposed to form the sum and difference wave. The simulation result shows the suitable jamming style could be chosen by jamming distance and the adaptive diagonal loading algorithm could form a deep zero and good shape wave.
