Airborne IR point-detection system

摘要

Abstract: An airborne IR system for the detection of aerial point sources has been designed. The sensor uses a detector based on a vector of elements. The coverage of the horizontal field of regard is achieved by scanning the complete sensor while vertical coverage is obtained by the detector's IFOV. The system is integrated into an airborne stabilized payload. System design considerations including selection of the spectral band, sensor optics and tradeoffs of SNR vs. horizontal revisit period, were made by using an IR point detection system design code. This code was used to calculate system performance in a clutter-free background.!10
