Abstract

The invention discloses an interference signal detection method, a mutual interference suppression method, a mutual interference suppression device, a sensor and equipment. The detection method comprises the following steps of: sampling a filtered receiving signal of a frequency-modulated continuous wave sensor to obtain a sampling signal, the sampling signal comprising a plurality of sampling points and signal units in one-to-one correspondence with the sampling points; acquiring signal amplitude difference values between the signal units corresponding to the adjacent sampling points; and determining that the signal units with the absolute value of the signal amplitude difference value greater than a detection threshold have interference signals. The detection method can effectively detect various forms of interference signals, can improve the precision of interference signal detection, and is beneficial to accurately removing interference signals as much as possible.

Description

technical field [0001] The present invention relates to the technical field of sensors, and more specifically, to a method for detecting interference signals, a method for suppressing mutual interference, a device for suppressing mutual interference, a sensor and equipment. Background technique [0002] Linear Frequency Modulation Continuous Wave (LFMCW for short) sensors are widely used in fields such as communication and target detection. [0003] However, when multiple LFMCW sensors are applied in the same scene, they will interfere with each other, that is, interference signals in the shape of spikes or oscillation pulses will be generated in the signals received by the sensors, which will reduce the working performance of the sensors. [0004] At present, it is generally judged whether it is an interference signal by the amplitude of the sampling value. However, since the magnitude and amplitude ratio of the interference signal and the normal signal are not easy to be ...
