<p>PURPOSE:To always obtain an operation state in which a maximum dynamic range is obtained by applying the output signal of a receiver to digitized memory of two-channel constitution. CONSTITUTION:A signal received from an antenna 1 is inputted to the receiver 6 through a transmission/reception switch 2 and a limiter 5. The output signal of the receiver 6 is branched and inputted to the digitized memory 9. The memory 9 has two channels; a received signal of a transmission/reception cycle is stored in the 1st channel and the weighted mean signal of plural received signals is stored in the 2nd channel. Those storage contents are sent to the gain control terminal of the receiver 6 as a signal STC for receiver control through an adder 11, filter 12, amplifier 13, etc., to allow the receiver 6 to operate in invariably the best state, suppressing a clutter automatically.</p> |
