The main stages of receiving and processing a linear frequency modulation (LFM) signal reflected from a point moving target are considered. When calculating the phase components of the received LFM signal, the principle of time scale transformation is used, which manifests itself in the mutual movement of the target and the radar station (radar) with pulsed radiation. At all stages of processing the LFM signal, including frequency transfer, quadrature demodulation (selection of the complex envelope of the signal) and matched filtering, the amplitude and phase functions of the signal are determined, allowing coherent processing of a batch of radio pulses. The analysis of the phase structure of the LFM signal is carried out, as a result of which the main phase components are determined, which are taken into account during interperiod signal processing in high-resolution radar.
