Claim 11:
12. The electronic device according to claim 11, wherein the preset rule for judging false detection comprises:
in a case that no adjacent ultrasonic radars of the to-be-judged ultrasonic radar returns obstacle coordinates, if the coverage range of the to-be-judged ultrasonic radar has a coverage range of single ultrasonic radar or an overlapped coverage range of two ultrasonic radars, it is judged there is no false detection; if the coverage range of the to-be-judged ultrasonic radar only has an overlapped coverage range of three ultrasonic radars, it is judged there is false detection;
in a case that one adjacent ultrasonic radar of the to-be-judged ultrasonic radar returns obstacle coordinates, it is judged there is no false detection;
in a case that two adjacent ultrasonic radars of the to-be-judged ultrasonic radar return obstacle coordinates, it is judged there is false detection.
