Abstract

To attain fast and accurate parameters estimation of LFM signal with low SNR, a novel estimation method is presented. In this method, LFM is received with dual channel preamplifier so that noises in LFM signals are uncorrelated, parameters are estimated by using modulus of received LFM signals fractional order cross spectrum and cubic splines interpolation. Numerical simulation shows that the presented method is with good noise immunity, high precision of parameters estimation.
