Title: Microwave detector
Inventor: ONO HISAO
IPC: G01S7/38
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a microwave detector capable of detecting microwave of objective frequency without reacting to disturbance wave. SOLUTION: In a microwave detector detecting a microwave in a specific band and outputting an alarm, a microcomputer 10 as a disturbance wave detection means detecting disturbance wave other than detection objective is provided and the disturbance wave information detected with the microcomputer is stored in a memory 11. Based on the disturbance wave information stored in the memory, whether the received microwave is a disturbance wave or the objective wave is discriminated. In the case it is judged as a disturbance wave, the alarm is not output. The microcomputer monitors the output state of the detection signal of the microwave output from a signal discrimination circuit 6, for example and gains frequency information during the output by obtaining the output voltage of a control voltage generator 9.  Then, in the case signal of a frequency is continuously received for a certain time period or more, it is judged as a disturbance wave.
