Abstract
An infrared radar system. The system includes an infrared laser and associated controller which are adapted to provide a succession of transmit pulses having a relatively high intensity spike portion followed by a relatively low intensity quasi-CW portion. An optical system directs the transmit pulses to a target scene and collects infrared radiation reflected from the scene. The collected radiation is imaged on a heterodyne detector array together with a locally generated reference infrared beam. A range network is responsive to signals from the detector array to provide signals representative of the range of objects in the target scene. A moving target indicator network is responsive to signals from the detector to provide signals representative of the velocity of objects in the target scene.
