Design and development of information processing system for space target detection and recognition

Abstract

Space target detection and recognition is the premise of competing for the advantage of space information and the important data source of space situation awareness. With the increasing space activities and threats such as space rendezvous and emergency launch, the demand for emergency detection and identification of space targets is becoming more and more urgent, and the demand for fast emergency and high-precision measurement of optical characteristics of space targets is also put forward. This paper introduces the space target observation information processing system based on camera array, which is being developed. The system is mainly used for space non cooperative target emergency measurement, and mainly includes four parts: firstly, the hardware basis of the whole information system is camera array optical measurement system; secondly, the system is based on STK and MATLAB two software joint platform, through the interface provided by STK/Connect and MATLAB interactive connection, through the MATLAB commands and instruction set to achieve the interactive use of data between the two software, as well as the collection and creation of charts and reports; third, the key technology of software development, namely the main function module The module mainly includes: initial orbit determination, orbit prediction, space target feature extraction based on optical characteristics, and space target recognition; finally, the whole software system is developed through the integration of the above four functional modules
