Embodiment 1

[0052] In the first aspect, the present invention first proposes a radar servo system that works while traveling, see figure 1 , the system includes:

[0053] Moving platform carrier 1, high dynamic turntable 2, stable platform 3, and radar front structure 4;

[0054] The moving platform carrier 1 is used as the carrier of the radar servo system, which is rotatably connected to the vehicle, and is used to generate a large-angle turning motion when the radar finds the target;

[0055] The lower end surface of the high dynamic turntable 2 is rotatably connected to the moving platform carrier 1, so as to complete motion compensation when the moving platform carrier 1 is rotated at a large angle;

[0056] The stabilized platform 3 is used for vertical compensation for the radar servo system, and includes a platform carrier 31, a plurality of evenly distributed platform electric cylinders 32, an angle gyroscope for detecting the angle of the stabilized platform 3, and a A positio...

Embodiment 2

[0070] In a second aspect, the present invention also provides an adaptive adjustment method for the above-mentioned radar servo system working while traveling, see Figure 4 , the method includes:

[0071] S1. Obtain the instantaneous speed when the moving platform carrier 1 produces a large-angle turning motion;

[0072] S2. Obtain the post-compensation speed of the high-dynamic turntable 2 based on the instantaneous speed of the moving platform carrier 1 and the predetermined speed of the high-dynamic turntable 2, and complete the motion position compensation of the system based on the post-compensated speed;

[0073] S3. Adjust the telescopic amount of the platform electric cylinder 32 to complete the vertical compensation of the system;

[0074] S4. Adjust the telescopic amount of the front electric cylinder 42 to compensate for the angular offset generated by the normal phase angle of the front plane during the adjustment process of the platform electric cylinder 32.

Abstract

The invention provides a radar servo system working in advance and a self-adaptive adjustment method thereof, and relates to the technical field of electromechanical servo control. The invention provides a radar servo system working in marching, which comprises a radar servo system composed of a movable platform carrier, a high-dynamic turntable, a stable platform and a radar array plane, and then an adaptive adjustment method of the system is utilized to firstly obtain the instantaneous speed when the movable platform carrier generates large-angle turning motion; then, the compensated speed of the high-dynamic turntable is obtained based on the instantaneous speed of the mobile platform carrier and the set speed of the high-dynamic turntable, and motion position compensation of the system is completed; adjusting the expansion and contraction amount of the platform electric cylinder to finish the vertical compensation of the system; and finally, the expansion and contraction amount of the array surface electric cylinder is adjusted to compensate the angle offset generated for the array surface normal phase angle in the adjustment process of the platform electric cylinder. According to the invention, the vehicle-mounted radar can be rapidly and accurately adjusted while the vehicle is moving.

Description

technical field [0001] The invention relates to the technical field of electromechanical servo control, in particular to a radar servo system working while traveling and an adaptive adjustment method thereof. Background technique [0002] When the ground vehicle radar works, the radar is generally transported to a certain position and erected, and then the search mode is turned on. However, the increasingly fast combat requirements have also put forward motorized combat indicators for the vehicle radar. Target search and tracking has gradually become a major combat mode of modern warfare. However, various complex terrain environments put forward higher requirements for the stable work of the radar. [0003] When the radar is working on the moving vehicle, after finding the target, the moving platform carrier as the vehicle load needs to complete the angle rotation to make the electronic equipment of the whole vehicle face the target. Angle error. In addition, when the veh...
