Синтез бортовых приемных устройств совмещенной обработки радиолокационных и информационных сигналов беспилотных летательных аппаратов малого класса

Abstract

The synthesis of a device for synchronous reception of radar signals, in the parameters of which information messages are integrated, has been carried out. The proposed approach is relevant for increasing the information exchange capabilities under the conditions of limited onboard small class unmanned aerial vehicles resources, critical to the mass of target loads, their power consumption and electromagnetic compatibility. The consecutive implementation of the proposed approach, based on the theory of joint filtering of discrete random and continuous Markov sequences is considered. It makes possible to synthesize an algorithm for a quasi-coherent receiver’s operation of discrete radio signals with the intra-pulse keying against the white noise background. The noise immunity characteristics of the receiver synchronization system were calculated, allowing for a given transmitter power to appropriately select the synchronized generator parameters and vice versa. The feature and advantage of the synthesized synchronization system is a implementation of the accumulation principle when receiving clock pulses.
