Abstract

The outputofmatched filters for linear frequencymodulation continuouswave (LFMCW) signalswas analyzedwith period ambiguity function. Frequencyweighting is effective to depress range side lobes and improve multi-target resolution, but itwidensmain range lobes in the same time and leads to loss in signal to noise ratio (SNR) of the output ofmatched filters forLFMCW signals. The loss ofSNR is 3. 52 dB, by takingHanningweight as an example.
