Quasioptimum of processing broadband LFM signals

It is considered technique of processing broadband HF LFM signals which allowing constructing transfer function radio channel with multipath effect diffusion. The scheme of a signal and noise is described on a receiver exit that gives the chance estimations of spectral density of noise in a wide strip. It is presented technique of quasioptimum filtration LFM signal and efficiency is experimentally shown.
