ABSTRACT:
A Method and Apparatus for Enhancing the Detection of Weak Emitters provide an enhanced method to eliminate the fake hits of a moving weak signal detection system. The method and apparatus have the abilities stated in the previous U.S. patent application Ser. No. 11/332,801 filed by this author, to do moving detection of weak signals, even in dense urban environments. Secondly, the method and apparatus includes additional antennas and hardware boards, in order to verify authenticity of detected targets. Thirdly, the method and apparatus include appropriate DSP algorithms loaded to program the mission. Fourthly, the method and apparatus are enabled to accurately determine the tangential distance of the target from me vehicles centerline. Finally, the method and apparatus provide the ability to continually discard false targets based upon the information provided by these approaches.
