Qi Liang Zhang, Qing Sun, Yong Sun · Advanced materials research · 2011
Linear-LM pulse-compression signal has been widely used in modern radar for its characteristics of far detection range and strong ability of anti-jamming. SNR of Linear-FM pulse-compression 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, SNR estimating arithmetic in frequency domain 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.
