PURPOSE:To decrease the number of multipliers which are costly parts by using a large number of shift registers, demultiplexers, and accumulators and making maximum use of the processing speeds of multipliers. CONSTITUTION:The receiving echoes stored in shift registers 8 are multiplied by the coefficients stored in shift registers 9 by multiplexers 13 in multipiers 4, and the outputs of the multipliers 4 are inputted to demultiplexers 10. The outputs of the demultiplexers 10 are stored in accumulators 5 via demultiplexers 11. The images which are beam-compressed with respect to range bins are obtained in an output device 12 with multiplexers at every fixed time. |
