Abstract

SNR estimation of LFM signal detection is often applied in radar, mobile communications, Radiolocation and seismic exploration with vibrator. The common method of LFM signal detection is correlation, which can not only be used to explain time delay in Multipath Propagation, but also to estimate SNR in detection of output signal. The records of signal plus noise before the signal detection are called System Input, while the records after the signal detection are called System Output. In this paper, SNR estimation method of LFM signal detection before System Input and after System Output is given. The simulation result indicates that this method is correct.
