Research of Characteristic Extraction Algorithm of Ballistic Missile Hyperspectral Databased on Horizontal Traversing Time

Abstract

A characteristic extraction algorithm of the ballistic missile hyperspectral data based on the horizontal traversing time is studied. The ballistic missile hyperspectral data of imaging spectrometer based on near-space platform is generated by numerical method. The characteristic of the ballistic missile hyperspectral data is extracted using the characteristic extraction algorithm based on the horizontal traversing time. The simulation result show that the characteristic extraction algorithm is easy to implement and low complexity. The characteristic, which extracted by this algorithm, is enough to represent the speciality of the ballistic missile hyperspectral data. The characteristic is not sensitive to disturbed signal and improve the timeliness of the following object matching and recognition.
