Abstract
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.
Highlights
It is well-known that the development of computers has led to the fact that the mathematical operations in electronic devices become fulfilled by means of discrete mathematics [12, 03]
That’s why the aim of this paper is the scientific study of the adaptive noise whitening algorithm in the HF band in the reception of a continuous chirp signal, its program implementation and experimental research using the platform USRP

Summary
It is well-known that the development of computers has led to the fact that the mathematical operations in electronic devices become fulfilled by means of discrete mathematics [12, 03]. This provides significantly higher precision math operations. The creation of universal hardware platform, implementing software and RTS with different functionalities is of particular importance Extensive use of SDR technology provides versatile family of programmable transceivers (USRP), Company Ettus Research [04] configurations with different frequency bands and supports for control and programming software such as GNU Radio, NI LabVIEW, MathWorks Matlab, HDSDR and others. That’s why the aim of this paper is the scientific study of the adaptive noise whitening algorithm in the HF band in the reception of a continuous chirp signal, its program implementation and experimental research using the platform USRP
