Embodiment Construction

[0021] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0022] When the grass and other vegetation are blown by the wind, it is characterized by swinging left and right or back and forth, which deviates from the position of the grass in the static state, but the shaking or swinging of the grass and other vegetation must be within a range of variation. Such as figure 1 As shown, assuming that the range of change is R, the moving position ...

Abstract

The invention is applicable to the technical field of radar detection, and provides a radar false alarm filtering method, terminal equipment and a storage medium. The method comprises the following steps: acquiring a sequence number of first radar data corresponding to a target and a first position of the target after a radar detects the target; acquiring second radar data according to the sequence number of the first radar data; when the second radar data contains the target, identifying a second position of the target according to the second radar data; and when the distance between the first position and the second position is smaller than a preset first distance threshold value, determining that the target is false alarm information, and filtering a record corresponding to the target.Due to the fact that the swing amplitude of vegetations such as grass and the like under the action of wind is limited, by setting the reasonable first distance threshold value, the radar false alarmcaused by shaking or swinging of the vegetations can be efficiently and reliably identified, so that the problem that a reliable technology is lacked to filter the false alarm on the millimeter wave radar detection due to vegetation shaking at present is solved.

Description

technical field [0001] The application belongs to the technical field of radar detection, and in particular relates to a method for filtering false radar reports, a terminal device and a storage medium. Background technique [0002] At present, millimeter wave radar has been applied in important places such as prisons, outposts, borders, airports, oil fields and substations, playing an important role in intrusion detection and real-time alarm. In the scene detected by the radar, vegetation such as grass may shake due to the wind, causing false alarms. The magnitude of the wind and the luxuriance of vegetation such as grass will cause changes in the speed of vegetation shaking, which may cause a situation that cannot be distinguished from the speed of pedestrians. In addition, the reflection area of ​​vegetation such as grass may also be close to that of people, which may also cause misjudgment. At present, there is no reliable technology to filter out such false alarms, wh...
