<p>PURPOSE:To attain to minaturize the titled equipment and to reduce the cost thereof, by providing a coherent integration circuit of one circuit to the difference (DELTA) signal system of the receiving signals from two antennae and successively processing the target detected by the sum (SIGMA) signa system of the aforementioned receiving signals. CONSTITUTION:Range memories 21a-21d store a complex input signal corresponding to one transmission at every range cell to store signals corresponding to four transmissions as a range memory group. The detected range cell number and filter number of an target are successively sent corresponding to the number of targets from a SIGMA target detection circuit not shown in the drawing and stored in target memory 25. The signal of the range cell number stored in the target memory 25 is read from the range memory group 21 and the range memories 21a-21d are successively changed over by a change-over switch 22 and, in synchronous relation to this change-over operation, the complex multiplication coefficient generated in a multiplication coefficient generation circuit 26 is controlled so that the target memory 25 is brought to the same response as the stored filter number. The foregoing operation is successively performed with respect to the target stored in the target memory 25.</p> |
