METHODS AND APPARATUS FOR DETECTING CONCEALED WEAPONS
First Claim
1. A system for detecting a threat, the system comprising:
- a transmitter that transmits a signal in the direction of a potential threat;
a detector associated with the transmitter which detects a reflected portion of the signal;
a processor associated with the detector; and
a display associated with the processor which displays a visual depiction of a scene that includes the potential threat, wherein the processor causes the display to indicate the segment of the depiction which is aligned with the aiming direction of the transmitter when the detected signal exceeds a threshold.

Abstract
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).
