Abstract
The paper presents models that allow us to determine the influence of the primary parameters of a moving radar on the features of secondary signals that occur in the receiver when calculating the range of a moving target. This makes it possible to model various signal processing methods, determine the limitations of these methods, and formulate recommendations for the construction and the hardware and software solutions that should be included in the scheme of a moving radar that tracks a moving target. It has been shown that applying an equilateral triangular LFM law with period 20 μs in a probing signal with carrier frequency 24 GHz and frequency deviation 250 MHz makes it possible to determine the range of a moving target relative to a moving radar. The distance between them is defined uniquely using a coherent processing of received signals. The ideal case of signal propagation has been considered.
