ABSTRACT:
There is provided an apparatus 10 for transceiving millimeter electromagnetic waves (MEW) creating a high resolution image of a field of view sensed by a flexibly resilient tapered slot antenna 12 formed with a resonant cavity 18 and a transformer horn 19; the antenna is affixed to solenoid unit 20 for imparting a vibratory force to the antenna causing it to scan a field of view. There is provided an integrated circuit signal processor chip 32 and a MEW signal affixed to the antenna 12. A 2 D amplitude modulator 34 is affixed to the leading edge of the antenna 12 adjacent the transformer horn 19 to impart orthogonality to the MEW signal that is transceived in order to achieve a 2 D azimuthal scan. The sensed signal is matched in the processor 32 which has input a template of an orthogonally power distributed beam by auto-correlation to the template.
