project background
The "Reserve Antiaircraft Antiaircraft Division's Artillery Weapon System Technical Improvement Project" is a project requested by the Shanghai Army Reserve Antiaircraft Division, developed by the Shanghai Pudong Center (hereinafter referred to as the "Pudong Center"), and approved by the Shanghai City Science and Technology Commission. The nature of the project is the "Air, Space and Civilian Use" special plan of the Municipal Science and Technology Commission. The project is to carry out technical improvements based on the active artillery weapons of the Reserve Antiaircraft Gun Division, and develop an air situation conversion controller and a portable missile launch autonomous combat system (hereinafter referred to as the "Missile Launch System") to improve the comprehensive combat effectiveness of active equipment.
Main development content
Air situation conversion controller
The air situation conversion controller is connected and communicated with the air situation network, the superior combat command system and the photoelectric fire control instrument respectively. It is used to receive and process the air situation information connected to the anti-aircraft artillery company and convert it into target guidance information of the photoelectric fire control instrument, so that the photoelectric fire control instrument can quickly capture targets and solve the problem of difficulty in searching and hunting targets; At the same time, the real-time combat information of the photoelectric fire control instrument is uploaded to the superior combat command system, so that the superior command can grasp the company's combat situation.
missile launching system
The missile launch system includes an infrared detection tracker, a fire control computer and a servo system. It can realize communication connection with the active "portable missile platoon combat command system". It can receive its target indication and combat command information, and automatically, accurately and quickly Capture and track air strike targets to overcome the problems of full capture and tracking targets and long combat response time faced by artificial shoulder-carried launches, and has the ability to fight in complex electromagnetic environments and at night.
