Target signal recognition system based on rotor wing unmanned aerial vehicle-mounted equipment and ground equipment

Abstract

The present invention relates to a target signal recognition system based on rotor wing unmanned aerial vehicle-mounted equipment and ground equipment and belongs to the technical field of communication reconnaissance. With the system adopted, the problem of the unsuitability of air communication detection equipment to long-time detection, the problem of the relatively long signal return time of the air communication detection equipment, the problem of short distances between ground communication detection equipment and the problem of the long signal processing time of the ground communicationdetection equipment can be solved. The system comprises rotor wing unmanned aerial vehicle-mounted equipment and ground equipment; the rotor wing unmanned aerial vehicle-mounted equipment is used forreceiving external real-time target signals, identifying the frequency band of the target signals, performing optimization processing on the target signals according to the identified frequency band,amplifying the obtained signals which have been subjected to optimization processing and forwarding the amplified signals to the ground equipment as forwarded signals; the ground equipment is used for performing feature vector extraction on the forwarded signals, performing double correlation operation on obtained feature vectors according to mapping relations between signals stored in a databaseand the target feature vectors so as to obtain a signal type and a carrier target and completing the identification of the target signals. According to the system, the double correlation operation identification technology is adopted, and therefore, target recognition is high in precision and reliable.

Description

technical field [0001] The invention relates to the technical field of communication reconnaissance, in particular to a target signal recognition system based on rotorcraft-mounted equipment and ground equipment. Background technique [0002] The principle of communication reconnaissance technology is to obtain the law of the enemy's communication activities through the detection, identification and analysis of the communication signals of the non-cooperating party, and then grasp the state of the enemy's communication system and determine the location of the target radiation source. According to different loading platforms, communication reconnaissance equipment can be divided into different loading forms such as fixed station, vehicle-mounted, ship-borne and airborne. The working principle of each loading platform is basically the same, but different loading forms are selected according to the mission environment. [0003] At present, air communication reconnaissance equip...
