摘要： A method and system for using a single transceiver to correlate radar position data with target identification data. Two transceivers, operating in round trip delay mode, can be used to provide two possible positions for a given target when radar coverage is lost or unavailable. Three transceivers can be used to provide actual position of a given target using round trip delay data only.

摘要： Methods and Apparatus for early detection and identification of a threat, and alerting against detected threats, such as individuals wearing or carrying explosive materials and/or weapons, e.g., suicide bombers and other terrorists, at a great enough distance to limit loss of life and destruction of property are disclosed. The methods comprise transmitting a signal in the direction of a potential threat, measuring the detected reflected signal, and comparing the signal level with a threshold indicative of a threat. A monitor is employed to display the threat and attributes of the detected signals. The invention further illuminates the suspicious individual(s) with a Laser illuminator/designator and provides information about the distance to the suspicious individual(s).

摘要： An automated radar terminal system employs primary (noncooperative) and secondary (cooperating transponder) surveillance radar equipment to monitor the ensemble of aircraft disposed within a subject air space. A data acquisition subsystem supplies detected and verified aircraft transponder-emitted beacon messages, and derived parameters which characterize each message such as aircraft range and azimuth, to a data processing subsystem. The central processor and memory structure there included maintain the interrelated target scratch pad, data base and multiple display files for accurately and efficiently presenting flexible combined primary radar video-alpha-numeric displays which typically vary at each of plural controller display stations.
