摘　　要：基于常规监视雷达方程、结合稀布阵特点,修正给出了稀布阵综合脉冲孔径雷达方程推导,并分析讨论了该体制雷达的特有参数.通过对脉冲积累时间、等效功率孔径积的计算分析以及与常规雷达的探测威力对比,得出了该体制雷达具有作用距离远、探测慢速目标时脉冲积累时间长以及所需等效功率孔径积小等优点.该方程在论证和研究稀布阵综合脉冲孔径雷达探测威力方面更具有实用性,为进行该体制雷达初步设计提供了一个良好的工具.According to the conventional surveillance radar equation,this paper deduces correctively a radar equation for the sparse-array synthetic impulse aperture radar system in terms of the sparse-array characteristics,and analyzes the specific parameters of the system.By computational analysis of pulse accumulation time and equivalent power-aperture product along with comparison to the detection power of the conventional radar,this paper also show that the SIAR system has such advantages as far operating range,long accumulation time while detecting the slow speed target and small equivalent power aperture product,etc.The given radar equation is of availability for studying of the detection power of the sparse-array synthetic impulse aperture radar,providing a better tool for the preliminary design of the radar system.
