機。[Claims for Utility Model Registration] (1) A shift register 14 that stores received signal waveform data of a distributed waveform consisting of a plurality of words while moving it in accordance with a signal system clock, and a coefficient sequence of transmitted waveform data. a kernel memory 15 for storing and determining a correlation with the data of the shift register 14; an output for each tap of the shift register 14;
A multiplier 16 that multiplies the output of each tap of the kernel memory 15, and an adder 17 that cumulatively adds the outputs of each multiplier 16.
and a data bus that monitors the output from the signal source 12 or part of the data stored in the shift register 14 and supplies data for rewriting the contents of the kernel memory 15 at the time when the signal is at a low level. and an address bus to the shift register 14 and the kernel memory 15.
11. A distributed compression type pulse echo system transceiver characterized by comprising: (2) Claim 1 characterized in that a monitor register 21 for monitoring the received signal waveform by the μPU 11 is provided instead of the shift register 14.
The distributed compression pulse echo system transceiver described above.
