В работе предложен метод решения проблемы в области обработки радиолокационных сигналов с линейной частотной модуляцией (ЛЧМ), обеспечивающий компенсацию нелинейных изменений радиальной скорости локационного объекта (ЛО) при его маневрировании. Метод основан на компенсации искажений радиолокационных сигналов, отраженных от ЛО, вызванных нелинейным характером изменения радиальной скорости при маневрировании в предположении линейного изменения скорости за время когерентного накопления (КН). Приведены результаты моделирования обработки сигналов с реализованным методом компенсации. A method for solving the problem in the field of radar signal processing with linear frequency modulation is proposed. The method provides compensation for nonlinear changes in the radial velocity of a aircraft during its maneuvering. The method is based on the compensation of reflected pulses distortions caused by the nonlinear nature of the change in radial velocity of a aircraft during its maneuvering. It is assumed that during the time of doppler process the radial velocity changes linearly. The results of signal processing simulation with the implemented method are presented.
