A device for distance controlling objects with dispersive-frequency companding of finite signals comprises series-connected single-sideband modulator (SM), linear-frequency modulator (LFM) and dispersive delay line (DDL) of specified order. Group delay (GD) function of this DDL have specified great steepness value, and at output thereof a channel low-pass filter is introduced, and at receiving end series-connected second SM, LFM are introduced, as well as second DDL with the same order and decreased value of GD function steepness. |
