Abstract. This paper compared the methods of spectral and correlation methods of noise signal processing  and made their assessment in relation to noise radar (NR) detection of ground objects. The paper represents the simulation results of processes of acquisition and object selection in noise radars, as well as the results of laboratory tests in single-channel and recirculating noise radar with sequential spectral analysis. The results of field tests with single-and dual NR are obtained on the layout in centimeter wavelengths. Using the layout at a wavelength of 3 cm the range of NR  and other energy parameters are estimated. The proposals for possible implementation of the processing devices  in NR with spectral signal processing, are justified.

Keywords: signal processing, noise signal, processing methods, object detection, correlation method, spectral method, single-channel radar system, comb filter, noise immunity, delay line.
