Pseudo-noise radar-type proximity detector, for use in industrial automatism, has processing unit to perform integration of function of correlation between transmission signal, modulated by a binary pseudo-random code, and reception signal

摘要

Proximity detector has a generation unit to generate a microwave frequency transmission signal modulated by a binary pseudo-random code. A reception unit receives a microwave frequency reception signal relating to the transmission signal. A digital processing unit (10) performs function of correlation between the signals, and performs integration of the function to find a target correlation surface permitting to detect presence of a target.
