Listening Post Surveillance Device (LPSD) AN/PPS-14

Abstract

The Listening Post Surveillance Device (LPSD), AN/PPS-14, was developed to increase the target acquisition capability of combat riflemen under conditions of poor visibility, such as would be caused by intervening foliage, darkness, and inclement weather. The development program started first with a shorter range CW radar system, but it rapidly evolved into a Pulsed Doppler system when the performance advantages and growth potential of such a system became apparent. The basic system operates at L-band, and the nucleus of the system is an adaptive and balanced signal processor which enables the radar to cope with a high clutter background while maintaining reliable target-detection performance. Tests in Boston and Aberdeen as well as operational evaluation at Fort Hood and in Vietnam showed the radar to be an effective device for detecting targets up to 130 meters in open space, and approximately 30 to 100 meters in foliage depending upon density and wind velocity.
