Abstract
According to one embodiment of the present invention, a directional radar transmitting and receiving system includes: a main control chip is configured to determine whether a pulse wave signal output by a sensor circuit board meets a triggering condition wherein each of a plurality of evaluation processes is satisfied, the evaluation processes including: a first evaluation process including: determining whether a width and an amplitude of the pulse wave signal meets a threshold amplitude; and a second evaluation process including: comparing a shape of the pulse wave signal output by the sensor circuit board with a pre-stored default triggering signal shape; and determining that the second evaluation process is satisfied when the shape of the pulse wave signal matches the pre-stored default triggering signal shape.
