A Microwave Technique for Detecting and Locating Concealed Weapons.

摘要

The subject of this report is the evaluation of a microwave technique for detecting and locating weapons concealed under clothing. The principal features of this technique are: persons subjected to search are not exposed to 'objectional'microwave radiation; a simple threshold detector can be used as the decision element obviating complex signal processing;system operation does not require extensive operator training;the resolution of the system (2inches x 2inches) permits location of a suspected weapon. This latter feature eliminates the need for a complete search of a passenger. Results of a laboratory measurement program are presented in support of the technique. (Author)
