<p>PURPOSE:To enable altering of a pulse compression ratio adaptive to a radar environment by arranging a several number of unit arithmetic devices of the same structure, for which filter coefficient signal delay devices are individually connected continual. CONSTITUTION:A filter coefficient output terminal 4 and a timing control signal output terminal 5 of a prestage unit arithmetic device are linked respectively to a filter coefficient input terminal 2 and a timing control signal input terminal 3 of a post stage unit arithmetic device to connect a plurality of unit arithmetic devices. Then, an operation mode controller 105 is operated to control a control circuit for a specified number of unit arithmetic devices so that the whole or a part of a specified number thereof are put in operation or at rest. At the same time, a switching of an output filter coefficient signal of a weighting coefficient generator 103 and an altering of a repetition cycle or the like of output timing signals of a timing controller 104 are performed corresponding to a change to increase or decrease of the number of the unit arithmetic devices. This facilitates the altering of a pulse compression ratio according to a radar environment.</p> |
