摘　　要：线性调频脉冲压缩信号具有作用距离远,抗干扰能力强的特点,在现代雷达中得到了广泛的应用。在对该雷达进行抗干扰性能定量评估过程中,通常需要对其信噪比进行实时测量,针对线性调频脉冲压缩雷达的特点,提出了信噪比实时估计算法,并采用高斯白噪声背景对该模型进行了仿真验证。仿真结果表明,该算法运算速度快,便于工程实现,可用于对线性调频脉冲压缩雷达抗干扰效果的评估。Linear-LM pulse-compression signal has been widely used in modern radar tor Its characteristics of far detection range and strong ability of anti-jamming. SNR of Linear-FM pulsecompression radar is needed to be measured real-time in the course of estimating its anti-jamming ability quantitatively. Aiming at the performance of this radar, real-time estimating arithmetic of SNR is put forward in this paper and the model is validated by simulating in Gaussian white noise background. Result shows that the high speed operation arithmetic is easy to implement and can be applied to estimating the anti-jamming effect of Linear-FM pulse-compression radar.
