低掠射角下传播因子对毫米波箔条RCS的测量影响

Influence of Propagation Factor on The RCS Measurement of Millimeter Wave Chaff at Low Sweep Angle

依据雷达传播理论、雷达测量原理和外场测控实践,结合有代表性的点目标和非相干延伸目标,分析了海面干涉因子,并对粗糙海面和平坦海面参与毫米波箔条云反射的程度进行了理论评估和实际测算,以求进一步认识和利用表面散射波对雷达测量的影响。

According to the theory of radar propagation,the principle of radar measurement and the practice of outfield measurement and control,this paper analyzes the sea interference factor combing with the representative point targets and incoherent extended targets,and performs the theoretic evaluation and actual measurement and calculation to the reflection degree of millimeter wave chaff cloud at the rough sea and smooth sea respectively,in order to further know and apply the influence of the surface scattered wave on radar measurement.
