Description

Technical Field

[0001] The invention relates to the field of radar detection, and in particular to a radar detection system based on a column-type antenna seat. Background Art

[0002] The radar detection system is a device that uses electromagnetic waves to detect the angle and distance of the target. It acquires target information by emitting detection electromagnetic waves and receiving the scattered echo of the target.

[0003] With the increasing demand for early warning detection of low-altitude targets, a composite detection system integrating multiple sensors such as radar and optoelectronics has become one of the best solutions for detecting, tracking and identifying low-altitude targets. During operation, the detection of radar equipment and optoelectronic equipment requires line-of-sight conditions with the target. In order to avoid mutual obstruction between devices, radar equipment and optoelectronic equipment in the composite detection system are mostly deployed in a stacked manner, that is, optoelectronic equipment is deployed in a stacked manner on top of a multi-faceted phased array radar. In this deployment mode, if the equipment located at the lower layer of the stack uses a turntable to realize the rotation of the radar array, the other sensors located above it will rotate with the turntable below, making it difficult for other sensors above to track the target. Therefore, in the composite detection system, radars mostly use a multi-faceted array or cylindrical array system, and achieve azimuth coverage through electronic scanning. The number of channels required by the radar system is huge, resulting in high costs and difficulty in use and promotion.

[0004] Another way to deploy a composite sensor is to directly install a support cover outside the radar to support the sensor above. For example, the Chinese invention patent application with publication number CN105898199A discloses a method for linking radar and photoelectric sensor, in which the radar is covered with a support cover, the photoelectric sensor is placed on the support cover, and the radar and photoelectric sensor are placed as a whole in a place where security is required, and connected to the control center using a network port; after the radar scans and finds the target, the radar will package and transmit the target's distance, azimuth, and movement direction and other information to the photoelectric sensor, and the photoelectric sensor will monitor and track the suspicious target, and the radar data information will be transmitted to the control center at the same time; the photoelectric sensor determines the angle to be rotated according to the azimuth information transmitted by the radar, rotates to the corresponding position, and transmits the azimuth, elevation and low angle and video image of the target to the control center; the control center analyzes and judges the received information and makes a decision on whether to take action on the suspicious target. In this deployment method, the support cover is not only costly, but also affects the detection performance. Summary of the invention

[0078] Working principle:

[0079] When the radar detection system based on the column antenna seat in the present invention is actually used, the system can provide an installation platform for the radar system and provide an installation base for the upper optoelectronic device 9, providing a radar system solution that is easy to integrate and use for the composite detection system. The present invention realizes the integrated design of the radar detection system through the central column antenna seat. The radar system uses the central column as the rotation core to realize the azimuth scanning of the array surface. At the same time, the central column provides an installation base for the upper optoelectronic device, realizing the effective integration of the azimuth machine scanning radar device and the optoelectronic device. Compared with the prior art, its overall cost is lower, and it can avoid the influence of the prior art solution on the detection performance, and the detection performance is better, which is convenient for integrated use.

[0080] The column-type antenna seat can drive the turntable assembly 3 to rotate around the column 2 through the azimuth drive mechanism 6, and the antenna drive mechanism 7 can drive the radar array 8 to swing to adjust its pitch angle, thereby realizing two-dimensional high-precision rotation of the antenna seat. In practical applications, the column 2 is used to carry other equipment such as optoelectronic equipment, and multiple detection devices that rotate independently can be installed in series through the column, providing an effective solution for the integrated design of microwave radar, optoelectronic equipment, etc., thereby solving the problem that the traditional antenna seat cannot realize the structural series connection of multiple rotatable detection devices and the technical problem that the traditional antenna seat cannot meet the requirements of carrying microwave antenna arrays and optoelectronic equipment at the same time. The present invention not only allows the antenna to rotate in two dimensions, but also provides an installation platform for optoelectronic equipment, and there is no interference between the two types of equipment.

[0081] The support flange 21 is used to support the bearing 42 and the turntable assembly 3 to ensure that the turntable assembly 3 can rotate freely while preventing it from sliding down along the column 2, and the structure is stable and reliable. The sealed space formed between the two sealing rings 34 can effectively isolate the bearing 42 from the outside world, prevent foreign objects from intruding, ensure that the bearing 42 can operate normally, and have a long service life. In actual applications, the cylindrical portion 35 cooperates with the top cover 22 to isolate the top of the column 2 from the outside world, prevent foreign objects from intruding, and protect the internal structure, ensuring that the antenna base can operate normally.

[0082] The turntable assembly 3 formed by the upper turntable 31, the lower turntable 32 and the truss-type connecting rod 33 has strong rigidity and good stability. The slewing bearing 41 can stably support the operation of the turntable assembly 3 and ensure that the turntable assembly 3 rotates smoothly. The motor 61 drives the gear 62 to rotate, and the gear 62 drives the inner ring of the slewing bearing 41 and the turntable assembly 3 to rotate relative to the outer ring of the slewing bearing 41 through the outer teeth of the outer ring of the slewing bearing 41. The overall structure is simple and the operation is reliable. The sealing cylinder 14 cooperates with the annular member 36 to separate the slewing bearing 41 and the azimuth driving mechanism 6 from the outside to prevent foreign matter from intruding, protect the internal structure, and ensure that the antenna seat can operate normally. In practical applications, the radar array 8 can be driven to swing up and down by the extension and retraction of the electric push rod, thereby adjusting the pitch angle of the radar array 8. The structure is simple and the operation is reliable. In practical applications, the frequency source 101 is used to realize the clock, local oscillator and other signals required for the operation of the radar system, and the information processing unit 102 is used for the control of the radar system and related signal processing. The overall structure and principle are simple and the application is reliable.
