The specific indicators are specified in the product standards (technical conditions). 4.2
Main technical performance requirements
4.2.1 Rotation range of each rotation axis of the antenna base
SJ3219--89
The rotation range of each rotation axis of the antenna base shall be determined according to the required airspace coverage, stability requirements and working range of the safety protection device of the radar. The range shall be specified in the product standard (technical conditions) 4.2.2 The angular velocity and angular acceleration of each rotating shaft of the antenna base are determined according to the target motion characteristics tracked or searched by the radar and the ship swing data. For radars with special requirements, the constant speed index and low-speed flatness index should also be specified in the product standard (technical conditions).
4.2.3 Natural frequency of antenna base
The natural frequency of the antenna base is an important indicator for measuring the stiffness design of the antenna base. The natural frequency of the antenna base is determined according to the accuracy and dynamic performance of the radar. Generally, the natural frequency is required to be greater than the bandwidth of the control loop. 4.2.4 Accuracy
The antenna base must ensure the specified accuracy, which is generally composed of the shaft system accuracy of the antenna base, the transmission chain accuracy, etc. 4.2.4.1 The shaft system accuracy consists of static and dynamic parts. This standard only applies to static shaft system accuracy. 4.2.4.1.1 Horizontal standard of the angular axis of the ship azimuth-pitch antenna mount The horizontal standard of the angular axis of the antenna mount refers to the verticality of the angular axis to the ship's reference platform. It is achieved by adjusting the azimuth axis of the antenna mount on land to meet the requirements. Therefore, the requirements under two conditions should be proposed and specified in the product standard (technical conditions): a. The requirements for the verticality of the azimuth axis of the antenna mount on land are greater than 1 for ordinary accuracy; between 30\ and 1 for medium accuracy; and less than 30" for high accuracy.
b. When the antenna mount is installed on a ship, the horizontal standard requirements of the angular axis of the antenna mount relative to the ship's reference platform have the same numerical range as a,
Note: When the two-axis stabilized antenna mount with a computer system is installed on a ship, the horizontal standard adjustment may not be performed, but the tilt deviation and deflection of the angular axis to the reference platform must be measured. The angle value where the maximum difference occurs is input into the computer, which then processes it.
4.2.4.1.2 Error of verticality of the pitch axis of the azimuth-pitch type antenna seat. The verticality of the pitch axis of the azimuth-pitch type antenna seat is the same as the verticality of the azimuth axis of the antenna seat on land. The meaning and measurement method are the same (generally measured on land before installation on ships). The ordinary accuracy is greater than 1,; the medium accuracy is between 30" and 1/; the high accuracy is less than 30". 4.2.4.1.3 Verticality of the longitudinal and transverse axes of the mechanically stabilized platform. For medium-precision stabilized platforms, the verticality of the longitudinal and transverse axes is required to be less than 1. 4.2.4.1.4 Horizontal standard of the mechanically stabilized platform. The horizontal standard of the mechanically stabilized platform refers to the parallelism of the reference plane on the platform to the reference plane of the ship. For medium-precision platforms, it is required to be between 30" and 1. 4.2.4.2 Transmission chain accuracy
The transmission chain accuracy of the antenna base is mainly composed of transmission error and idle motion error. This standard only specifies the idle motion error requirements. In the product standard (technical conditions), according to the technical requirements of the radar equipment, transmission type, level, bearing, transmission parts accuracy, etc., the idle motion error requirements of the power transmission chain and the data transmission chain under the specified load (converted into the corresponding static moment) should be respectively proposed.
SJ321989
Ordinary precision power transmission chain idle motion error (low speed level) is greater than 5: medium precision is 1 to 5; high precision is less than 17:
Ordinary precision data transmission chain idle motion error (low speed level) is greater than 1; medium precision is between 30 and 1: high precision generally uses a coaxial data transmission device without idle motion error. If negative hysteresis is allowed, it should be specified in the product standard (technical conditions). 4.2.5 Static friction torque and dynamic friction torque
Medium and ordinary precision antenna bases can only provide static friction torque requirements. High precision antenna bases and antenna bases with high requirements for low-speed stability require dynamic friction torque indicators in addition to static friction torque requirements. The static friction torque and dynamic friction torque of the antenna base should comply with the provisions of the product standards (technical conditions). 4.2.6 Noise
