“…To implement the method which is proposed in this work, it is necessary to organize the operation of the signal processing device for digital processing in such a way as to ensure the fulfillment of both the listed tasks and additional ones, which are in the selection of echo-signals by the correlation features properties of their complex bypass, and therefore only quadratic ADC implementation or detection [24][25][26]. Signal processing device on the basis of a programmable processor consists of two interrelated parts as shown in Figure 10, the device of gain and signal conversion and the actual programmable signal processor.…”

A new radar system for digital signal processing before detection is proposed. These are the guidelines for selecting an intermediate frequency for signal processing. The features of signal processing in the case of echo-signal selection by the features of the correlation properties of their complex bypass are described. This paper presents the study of ambiguity function (AF) when processing complex radar signals. In this work, the AF synthesis was performed considering non-determined components and the presence of phase-frequency instability. The received result enhances the potentials for distinguishing an incoherent radar signal. The numerical simulation results of received AF are presented. Considering fluctuation components in the complex AF, depending on the laws of the distribution of amplitude and frequency fluctuations and their parameters, allowed to get the gain in the width of the main lobe from the units to tens of times. Paper represents original analytical expressions for AF of radio-signals modulated by narrow band random processes with various distribution laws.
