In this example, the spatial parameters may include elevation and azimuth angles, the current array configuration may be the current phased array antenna configuration control scheme, and the current array configuration switching marker can be used to mark the switching of the array configuration.

[0050] In step S103, array switching is performed according to the spatial parameters of the target in the next beam switching cycle and the preset array switching rules. In this example, the spatial parameters of the target in the next beam switching cycle are compared with the current spatial parameters, and array switching is performed according to the array switching rules, thereby realizing continuous tracking, detection, and communication of moving targets by the beam and avoiding signal interruption caused by repeated array switching.

[0051] In some embodiments, the vehicle-mounted conformal phased array antenna includes at least five array surfaces, with the first and fifth array surfaces covering both sides of the vehicle platform, and the remaining at least three array surfaces disposed on the top surface of the vehicle platform, forming corresponding angles with the respective first array surfaces. Specifically, as shown... Figure 1 and Figure 2 As shown in the illustration, the conformal phased array antenna in this embodiment is composed of five array surfaces: the first array surface 21, the second array surface 22, the third array surface 23, the fourth array surface 24, and the fifth array surface 25.

[0058] The angle between the beam and the XOZ plane is defined as the elevation angle, and the angle between the projection of the beam onto the XOZ plane and the Z-axis is defined as the azimuth angle.

[0059] Specifically, such as Figure 4As shown, in this example, a three-dimensional coordinate system for the conformal phased array antenna is defined. In this three-dimensional Cartesian coordinate system, the forward and backward direction of the conformal cabin is defined as the Y-axis, the left and right direction of the conformal cabin as the X-axis, and the direction above the top of the conformal cabin as the Z-axis. The angle between the beam and the XOZ plane is defined as the elevation angle, denoted by θ, with forward deviation towards the conformal cabin being positive and backward deviation being negative; the angle between the projection of the beam onto the XOZ plane and the Z-axis is defined as the azimuth angle, denoted by θ. This indicates that deflection to the left of the conformal cabin is negative, and deflection to the right is positive.

[0071] This application also proposes an implementation example of a beam coverage method for a vehicle-mounted conformal phased array antenna, specifically a vehicle-mounted conformal phased array measurement and control equipment employing a 5-array scheme. For example... Figure 5 There are four targets that need to communicate with the vehicle-mounted conformal phased array equipment. Assuming that the current array is working in multi-array synthesis mode 1, the array configurations corresponding to each target based on the above beam coverage strategy are shown in Table 3 below. According to the direction of motion, target 3 will enter airspace 4 at the next moment: S(4), then the corresponding array configuration will change from A 1,3 Switch to: A 1,4 ={23,24,25}.
