substantiation of the adaptive noise whitening algorithm is given in the HF
band when receiving a continuous chirp signal. The software implementation of
the algorithm is presented. Full-scale experiments were conducted, using the
developed device with a continuous chirp signal, based on the technology of
software-defined radio systems. It is established that whitening tends to
equalize noise level throughout the HF band. Some rare emissions of whitening
spectrum do not exceed the range of 10 dB.
