摘　　要：针对中近程搜索雷达发射信号参数设计问题,通过对雷达威力的推导,给出了雷达威力与发射信号占空比、宽窄脉冲探测距离衔接系数、探测目标RCS最小值、探测目标RCS最大值的关系公式。根据公式可以绘制出雷达威力与发射信号占空比的关系曲线,找出最优占空比、雷达威力系数和最优宽窄脉冲宽度比值,进一步得出脉冲重复周期和宽窄脉冲宽度。该方法为RCS范围确定提供了理论基础,为雷达模式设计提供了依据。Aiming at parameters design problem of transmitting signals for medium and short range search radars,by derivation of radar powers,such contents are presented,including the relationship formula of the duty ratio between radar power and transmitting signal,the cohesion coefficient of wide and narrow pulse detection distances,the minimum value of detected target RCS,and the maximum value of target RCS.According to this formula,the relationship curve between the radar power and the duty ratio of the transmitting signal can be drawn based on the formulas and the optimal duty ratio,the radar power coefficients and the optimal ratio of wide and narrow pulse width can be determined.Furthermore,the pulse repetition periods and the width of wide and narrow pulses can be found.This method can provide theory basis for determining the range of RCS and designing radar mode.
