Radar target classification method based on multiple FT-M6678 chips

Abstract

The invention discloses a radar target classification method based on multiple FT-M6678 chips, and the method comprises the steps: constructing a signal processing module which comprises a first FT-M6678 chip and a second FT-M6678 chip, and the first FT-M6678 chip and the second FT-M6678 chip are connected with each other; constructing a training data set by using multiple groups of collected radar echo data, generating a target classification template file by using the training data set, and storing the target classification template file to the first FT-M6678 chip; performing parallel preprocessing on the original radar echo data to be classified by using a second FT-M6678 chip, and transmitting the preprocessed data to be classified to the first FT-M6678 chip; and carrying out feature extraction and target classification identification on the preprocessed to-be-classified data in a multi-core polling manner by utilizing a core in the first FT-M6678 chip to obtain a target classification result. According to the method, the characteristics of FT-M6678 are combined, through a processing mode of combining multi-core parallel and multi-core polling, the requirement of real-time processing of target identification is met by utilizing limited hardware resources, and the problem of poor real-time performance of the existing radar target identification technology is solved.

Description

technical field [0001] The invention belongs to the technical field of radar, and specifically relates to a radar target classification method based on multiple FT-M6678 chips, which can perform real-time identification of different targets moving in the air and on the ground through the cooperative work of multiple FT-M6678 chips. Background technique [0002] FT-M6678 multi-core DSP (Digital Signal Processing, digital signal processor) is a domestic high-performance multi-core digital signal processor, containing 8 Feiteng M66x DSP cores (core 0~7), each core operating frequency is 1GHz, internal It has 32KB first-level program storage controller (L1P), 32KB first-level data storage controller (L1D), 512KB second-level storage controller (L2), and the on-chip shared memory is 4MB, which not only ensures the relative independence of data , and can share and reuse data. FT-M6678 supports two-level Cache, which improves the data and code access rate, and supports multi-core ...

AI Technical Summary

Problems solved by technology

The amount of data in the preprocessing stage is large, but the amount of data processed in the feature extraction stage and the prediction stage is very small. Directly adopting a single-core or multi-core parallel method will face two problems: 1. Hardware resources are wasted and cannot be fully utilized; 2. The real-time performance of target classification is difficult to meet
