情报雷达低空小目标探测能力评估方法研究

针对情报雷达探测低空小目标问题，综合考虑了大气传输损耗、大气折射、多路径效应、地面和海面杂波干扰、目标发现概率要求等有关因素，建立了多约束条件下的目标回波估算模型、低空探测杂波功率估算模型，给出了一种实用的低空小目标实际探测能力综合评估方法．并结合具体低空补盲雷达参数进行了仿真分析，验证了该算法的有效性．

Evaluation of Detection Capability of Low Altitude Small Target for Intelligence Radar

Aimed at the low altitude small target detection of intelligence radar, the estimation models of target echo and low altitude detection clutter power were set up in terms of some related factors of atmosphere transmission loss, atmosphere refraction, multipath effect, ground and sea clutter jamming and target detection probability, etc, and a useful comprehensive evaluation algorithm of detection capability of low altitude small target was given. Finally, by using the available parameters of low altitude blind-patching to simulate and analyze the proposed scheme, it shows that the evaluation algorithm is of great effectiveness.
