ABSTRACT:
Microprocessor controlled electronically scanned collinear array receiver stem includes a dipole antenna mounted atop the array to provide complete scan coverage from horizon to horizon. The microprocessor controls the scan angle and the frequency range to provide full search coverage for all scan angles in a hemisphere. Simultaneous angle tracking and frequency tracking are accomplished when the desired signal is acquired.
