Title:
【発明の名称】マイクロ波検出器
Document Type and Number:
Japanese Patent JP3329744
Kind Code:
B2
Abstract:
A microwave detector for detecting a target microwave signal carries out detection by dividing the target bandwidth into a plurality of partitioned bands which are each repeatedly swept a prescribed number of times, with the detected wave outputs from each sweep being added together to form an added detected wave output for each partitioned band, and due to mutual cancellation of the white noise, the presence of even a faint target microwave signal within a partitioned band will increase to a detectable level in the added detected wave output of such partitioned band, and because the detection process is carried out separately for each partitioned band, the microwave detector only needs enough memory capacity to store the added detected wave output of a single partitioned band.
