【摘要】 本文提出了雷达高度计的一种系统模拟方法。在已有数据和理论模型的基础上，提出了雷达回波强度的计算方法，并对这种新型高度计系统进行了计算机模拟。提出了一种目标信号检测算法，根据系统模拟结果计算出该高度计的发现概率和虚警概率，说明这种高度计可以用于各种飞机的测高。更多还原

【Abstract】 This paper presents a system simulation method of pulse Doppler radar altimeters with frequency agility.Based on available data and theoretical models,the method of computing the amplitudes of the radar returns and the computer simulation of this neW altimeters is presented. An algorithm of detecting targets is proposed and the probability of detection and the false-alarm probability of this altimeter are calculated according to the system simulation results,which shows this altimeter are calculated according to the system simulation results,which shows this altimeter can be used on all kinds of aeroplane to detect altitudes.更多还原
