Abstract

The invention discloses a digital radar simulation system, which comprises an emission subsystem, used for converting a baseband signal generated by a signal source into an intermediate frequency signal and simulating and generating radar position information and target position information; an echo generation subsystem, used for generating an intermediate frequency echo signal according to the radar position information, the target position information and the intermediate frequency signal; a receiving subsystem, used for determining a signal meeting a preset condition as a target echo signalaccording to the intermediate frequency echo signal; and a signal processing system, used for analyzing and processing the target echo signal to determine a distance from a target to a radar and / or aradial speed of the target relative to the radar and / or a pitching angle and an orientation angle which are pointed by the target relative to a radar beam. By the adoption of a modular design, a usercan efficiently design all hierarchical models and systems to design rich radar basic model libraries; the user can configure files conveniently; and the dependency of the simulation system on an editing environment is decoupled.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a radar digital simulation system and method. Background technique [0002] With the continuous development of radar systems and the increasing specialization of transmission signal forms, electromagnetic environments, and signal processing algorithms, it is necessary to establish a joint development environment to integrate radar-related majors and requirements at different stages of product development. In this joint development environment, designers of various disciplines can bring together their own models to conduct system simulation, performance testing, and algorithm verification of the radar, and analyze the impact on the system. In the simulation system of the existing mode, the user configuration files are cumbersome, the simulation system depends on the compilation environment, and does not have the ability to view the working status of the radar in real time.
