Multi-measuring-point synchronous identification method for thunder field target

Abstract

The invention discloses a multi-measuring-point synchronous identification method for a thunder field target. The method comprises the following three parts that (1) each detection extension carries out online detection and frequency spectrum refinement according to a synchronous detection instruction sent by a detection control host; (2) a thunder field target is identified and positioned by each detection extension according to the detection refined spectrum; (3) the detection control host integrates the detection identification data of the detection extensions to obtain a detection result; The method has the advantages that according to the working principle of the ground penetrating radar, the UWB pulse echo signals are subjected to frequency spectrum refinement, the signal modulation principle is applied, interference factors are considered at the same time, the criterion for recognizing the feature information of the thunder field target in the refined spectrum is summarized, and the recognized thunder field target is positioned; the system is used for a thunder field detection system composed of one detection extension set and seven detection extension sets, the safety of thunder field detection work is improved, real-time online signal processing is carried out, the efficiency is improved, and the false alarm rate is reduced.

Description

technical field [0001] The invention relates to a recognition method, in particular to a multi-measuring-point synchronous recognition method for a minefield target. Background technique [0002] Landmine is a kind of traditional weapon. It has been spread around the world because of its powerful power on the battlefield, and it has played a huge role in modern warfare; but there is still no effective mine detection equipment, and mine detection with a high false alarm rate The equipment has distrusted the fighters and cannot meet the status quo required by modern mine warfare. In the preset minefield, various mines can be set, including anti-infantry mines and anti-tank mines, which are collectively referred to as minefield targets. meters, buried 2-3 cm deep in the ground, and each column is 25-50 meters apart. In short, there are certain rules, and most minefield targets have metal detonators, which can be identified through metal characteristic detection. [0003] Trad...
