Abstract

Ladars have been designed for various applications but not adequately explored for airborne surveillance. A Moving Target Indicator (MTI) ladar concept is presented capable of detecting small aircraft at long ranges. Atmospheric attenuation for cloud-free lines of sight is controlled by operating wavelength selection and avoidance of long horizontal paths through the lower atmosphere. Atmospheric turbulence effects were found to be insignificant. The performance of the ladar is analyzed and subsystem requirements for lasers, detectors and spectrum analyzers are developed. A computer simulation capability was developed that allows prediction of the ladar signatures of aircraft.
