Infra-red active identification method for night time military targets

摘要

The method uses an Infra-Red illumination system (4) radiating a wavelength of 3 microns or lower. The illuminator illuminates the target (3), such as a helicopter, tank or firing post. Image returns from the target are detected by an infra-red camera (2) at the transmitted wavelength. The image is then analysed to identify the target.
