AI Technical Summary

Technical Problem

Existing phased array radar intermediate frequency signal simulation technology has significant bottlenecks in terms of real-time computation, especially when the array size is expanded, it is difficult to complete the real-time generation of the entire array signal within the radar pulse repetition period. Traditional solutions suffer from long development cycles, difficulty in functional expansion, and insufficient adaptability.

Method used

A heterogeneous computing-based approach is adopted. By decomposing the multi-target echo generation task into two dimensions, the computing units are divided into complex vector classes and sampling interpolation classes. Differentiated mapping is performed based on the computing power characteristics of heterogeneous computing nodes. By leveraging the advantages of high-parallel throughput nodes and low-latency response nodes, parallel computing and pipelined cascading splicing operations are realized to generate a full array intermediate frequency composite signal stream.

Benefits of technology

While maintaining programming flexibility and algorithm scalability, it realizes the real-time generation of intermediate frequency signals for large-scale phased array radar, solves the structural contradiction between computing power and real-time requirements, and improves the engineering practicality of the simulation system.

Abstract

This invention belongs to the field of radar signal simulation technology. It discloses a real-time simulation method for intermediate frequency (IF) signals of phased array radar based on heterogeneous computing. The method includes: receiving simulation scenario configuration instructions, parsing array topology parameters and beam scheduling timing description information, and generating simulation task description data; decomposing the multi-target echo generation task in two dimensions: array element channel dimension and pulse timing dimension, classifying the computational units into complex vector classes and sampling interpolation classes, and mapping them to corresponding heterogeneous computing nodes to generate task allocation maps; each node executes the computational units in parallel to generate component signal data, performs pipelined cascading splicing according to the beam pointing sequence timing beat, and sets signal continuity transition processing to generate a full-array IF composite signal stream; applying amplitude weighting and time delay compensation to the signal stream, and outputting a multi-channel synchronous IF simulation signal after digital-to-analog conversion; effectively resolving the structural contradiction between computational power and real-time requirements in IF signal simulation.
