单/双基地雷达的低空探测性能研究

Research on the low-altitude detection performance of monostatic and bistatic radars

从雷达方程出发,提出单、双基地雷达探测目标的判定式,通过实时采集典型目标的单双站雷达散射截面,计算出单、双基地雷达对该目标的低空探测范围图,得到有价值的结论。通过比较分析,证明双基地雷达在对目标低空探测方面优于单基地雷达,为双基地雷达用于工程实践提供了理论依据。

The determinant detection formulas of monostatic and bistatic radars are gained on the basis of radar equation. The detection coverage on a representative target at a low altitude is obtained by calculating the cross section of the monostatic and bistatic radars on this target in real time. Some valuable conclusions are reached. It is proved by comparison and analysis that bistatic radar is better than monostatic radar in low-altitude detection coverage, which gives a theoretic reference for the engineering practice of the bistatic radar systems.
