Reflected tv radio or radar beam

WebThe radar antenna does two jobs. First, it receives the high-frequency pulses from the transmitter, focuses them into a beam, and sends them into space. Second, it picks up reflected pulses coming from objects that have been struck by the beam. The antenna focuses the reflected waves and sends them to the receiver. WebWhen there are significant deviations from the "standard" atmosphere (extreme temperature and moisture inversions), the radar beam may be bent more sharply toward the earth or …
