低脉冲重复频率(PRF)脉冲雷达信噪比(S/N)的计算方法,通常是先算单一脉冲的信噪比,然后将此比值乘以积累脉冲数来得到一给定目标照射时间内的信噪比。高脉冲重复频率脉冲多卜勒雷达,一般是以发射信号频谱中心谱线功率为目标回波功率来计算雷达信噪比的,因为在这种雷达接收机中,必须保留发射信号频谱的中心谱线,而把那些PRF谱线去掉。本文所指出的两种雷达信噪比的计算方法,对匹配的发射-接收雷达系统是完全等效的。
Low pulse repetition frequency (PRF) Pulse radar signal-to-noise ratio (S / N) is calculated by first calculating the signal-to-noise ratio of a single pulse and then multiplying the ratio by the number of accumulated pulses to obtain a given target irradiation time The signal to noise ratio. High pulse repetition frequency Pulsed Doppler radar usually calculates the radar signal-to-noise ratio based on the spectral power of the center of the transmitted signal as the target echo power because in this radar receiver, the central spectrum of the transmitted signal spectrum must be preserved Line, and those PRF lines removed. The two radar signal-to-noise ratios, as noted in this article, are completely equivalent to matching transmit-receive radar systems.
