Scientific 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.
