Patent ID: 7411542

Claim:
A method of detecting a target with a radar system, comprising: a. generating a first beam of electromagnetic radiation in at least one first direction; b. generating a second beam of electromagnetic radiation in at least one second direction, wherein a second direction of said at least one second direction is substantially aligned with a first direction of said at least one first direction, said second beam of electromagnetic radiation in said second direction overlaps a main lobe of said first beam of electromagnetic radiation in said first direction, said main lobe of said first beam of electromagnetic radiation in said first direction is adapted to illuminate a valid target to be detected by said radar system, and a substantial portion of said second beam of electromagnetic radiation extends beyond said first beam of electromagnetic radiation in at least one third direction so as to provide for illuminating a false target to be ignored by said radar system; c. focusing at least one of said first beam of electromagnetic radiation and said second beam of electromagnetic radiation in at least one direction; d. generating a first signal responsive to receiving first reflected electromagnetic radiation of said first beam of electromagnetic radiation, wherein said first reflected electromagnetic radiation is reflected by an environment of said radar system; e. generating a second signal responsive to receiving second reflected electromagnetic radiation of said second beam of electromagnetic radiation, wherein said second reflected electromagnetic radiation is reflected by said environment of said radar system; and f. processing said first and second signals so as to provide for discriminating said valid target from said false target.
