Abstract

The invention provides a directional radar transmitting and receiving system, which comprises a sensor board and a main control board. A microwave oscillator of the sensor board transmits high-frequency microwaves through a transmitting antenna. A main control chip on the main control board performs pulse wave analysis. The included judgment elements are as follows: a first judgment element of judging the width and amplitude of a pulse wave signal to confirm whether the pulse wave signal is a clutter signal generated by the movement of a small object, if the pulse wave signal is a clutter signal generated by the movement of the small object, returning, and as the signal generated by the movement of the small object has a small amplitude and is not easily triggered, re-monitoring a next pulse wave signal sent by the sensor board; and a second judgment element of comparing the shape of the pulse wave signal currently output by the sensor board with a pre-stored default trigger signal shape, if the pulse wave signal does not match the pre-stored default trigger signal shape, determining the pulse wave signal as a clutter signal, and returning to re-monitor a next pulse wave signal sent by the sensor board. Interference signals are well eliminated, the accuracy of judgment is ensured, false triggering is avoided, and the reliability and practicality are improved.

Description

technical field [0001] The invention relates to a directional radar transmitting and receiving sensor board. Background technique [0002] The traditional radar transmission and reception is 360 three-dimensional transmission. When the radar transmission and reception trigger switch is used to control electrical equipment, it is easy to trigger by mistake and malfunction. For example, when it is installed in two adjacent rooms, each room is equipped with a radar transmission and Receive electronic switches to control their own lights. When someone enters one of the rooms, the power switch of the room is automatically closed to turn on the lights in the room, but the lights in the next room will be turned on by false triggers, so the current directional radar Since the key technical problems of the transmitting and receiving switch control device have not been solved, its application environment is subject to many restrictions, and it cannot be widely used. [0003] In addit...
