Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The invention relates to a dead zone tracking method and device for a directional antenna and a mobile tracking system. The method comprises: acquiring position and velocity of a tracking target relative to the directional antenna; determining whether the tracking target is within a tracking dead zone of the directional antenna according to the position and velocity; if yes, driving the directional antenna to rotate in a preset dead zone guiding mode. The method allows switching to the corresponding dead zone guiding mode when an unmanned aerial vehicle enters a tracking dead zone, so that full-course tracking is provided for a tracking target; temporary loss of the tracking target in the tracking dead zone is avoided; the tracking effect is better.

Description

【Technical field】 [0001] The invention relates to the technical field of tracking systems, in particular to a blind area tracking method of a directional antenna, a device thereof and a mobile tracking system. 【Background technique】 [0002] With the development and maturity of UAV technology, its application scenarios are becoming more and more extensive. A large amount of measurement and control data exchange is required between the UAV and the ground control system. Therefore, the mobile tracking system can be used to ensure the reliability of data transmission and improve the data transmission gain and anti-interference ability. [0003] The function of the mobile tracking system is to isolate the influence of the movement of the carrier on the attitude of the directional antenna during the operation of the carrier (such as a vehicle, ship, aircraft, etc.), and to ensure that the directional antenna is always aligned with the high-speed maneuvering UAV to achieve contin...
