Design method of radar communication integrated shared construction module architecture superheterodyne receiver

Abstract

The invention provides a design method of a radar communication integrated shared construction module architecture superheterodyne receiver, and aims to provide a rapid and efficient multi-purpose receiving complete machine design method. The method is realized through the following technical scheme of according to a superheterodyne system, firstly planning six common construction modules, namelya radio frequency front end module, a radar intermediate frequency module, a communication intermediate frequency module, a power supply module, a control module and a frequency source module; secondly, for the circuit principle of the six common construction modules, serializing a series of product libraries of the common construction modules; then designing a superheterodyne radar-communicationintegrated receiving complete machine, and respectively selecting the corresponding shared construction modules for combination according to an existing shared construction module product series in the design of the radar-communication integrated receiving superheterodyne receiver in combination with the technical index requirements to realize the radar-communication integrated receiving superheterodyne complete machine.

Description

technical field [0001] The invention relates to a design method for a superheterodyne receiver with a common building block architecture for radar communication integration, in particular to the application of a radar and communication integrated detection and reception system under the rapid construction of an electronic integration framework. Background technique [0002] Due to the high spectrum density, large signal bandwidth and complex spectrum pattern of the modern electromagnetic environment, higher and higher requirements are put forward for the signal receiving system. There are many types of receivers, and the characteristics of each type of receiver determine its application. Common receiver types include superheterodyne receivers, channelized architecture receivers, and zero-IF receivers. Among them, channelized receivers are constrained by factors such as large size, high power consumption, and difficult to control costs; although zero-IF receivers have a simp...
