AUTOMATIC CLUTTER REMOVING SYSTEM FOR RADAR EQUIPMENT

摘要

PURPOSE:To enable the removal of clutters automatically and properly from a signal received, by adjusting the amplification gain of the received signal according to the generation state of clutters to determine an STC waveform adapted to the state. CONSTITUTION:A memory 11 memorizes a received signal outputted from an amplifier 10 by one scan of an antenna 31 and based on the signal memorized, a decision section 12 detects the clutter distribution to determine a proper STC waveform according to the clutter distribution. Based on the STC waveform, an optimizing section 13 determines the attenuation level for the sensitivity suppression and based thereon, a gain adjusting signal is applied to an amplifier 10 to determine the gain. As a result, the reception signal suppressed in the clutter is outputted from the amplifier 10.
