Problems solved by technology

Because the computer spends a lot of time on storing data, it is difficult to guarantee high-speed storage, so it is difficult to achieve long-term continuous high-speed acquisition and storage by traditional methods
Traditional standard buses such as ISA, VL and MAC can no longer meet the requirements of modern data high-speed transmission

Abstract

The invention provides a device and method for collecting, storing, and analyzing radar echo data, wherein the device and the method are suitable for radar-related weapon products. The device comprises an acquisition module, a storage module, and a data processing module. The acquisition module carries out sampling on a radar echo signal to obtain radar echo sampling data and then sends the data to the storage module. The storage module is used for storing the radar echo sampling data. The data processing module is used for finding out a starting point spaced repeatedly of each radar by usinga sliding window search method. Therefore, the collection of high-speed echo data, high-speed storage and efficient processing of echo data are realized.

Description

technical field [0001] The invention belongs to the field of radar signal processing, and relates to a collection, storage and analysis device and method suitable for radar echo data, in particular to a design scheme for collection and processing equipment of high-speed radar echo data based on VPX architecture, and is applicable to radar-related weapons and equipment products. Background technique [0002] The detection, positioning and tracking of radar targets are mainly realized through the information extraction and processing of target echo signals. In modern radar signal processing, especially target detection and synthetic aperture radar (SAR) imaging, it is necessary to collect a large amount of radar echo data on site to analyze and study various characteristics of target echo signals, and provide information extraction and processing for the target. in accordance with. [0003] Modern radars have higher and higher requirements for resolution, so the signal is re...
