Vehicle-Mounted and Ship-Mounted Dynamic Tracking Antenna-The First Domestic Set
Project Name: ***Ka-band Offset Multi-Beam Fully Mobile Station
3.8-meter Ka-band feed multi-beam parabolic antenna;
The antenna surface is foldable, and the entire antenna can be stowed inside a cabin for transportation and relocation;
The central feed uses a corrugated horn to improve the antenna's primary channel performance, while the periphery employs a dense array of 22×22 multi-beam square horns, achieving a 5°×5° off-axis beam coverage;
It is used for tracking and angle measurement of telemetry signals from domestic DD (Dongfeng) and launch rocket tests on sea-based and land-based mobile platforms, known as "dynamic tracking";
This is the first set of shipborne tracking antennas developed by our institute and also the first set of common tracking antennas for both sea-based and land-based mobile carriers in China.
Rapid Capture of High Dynamics and Narrow Beams (High-Speed Targets, up to 15 times the speed of sound) on Moving Platforms.
Tracking of Highly Dynamic Targets with Compensation for Lag (Ka-band and beyond, ≥15).
Vibration Isolation for Moving Platforms (Ship Roll and Vehicle Sway Isolation, Ship Roll Isolation Degree ≥50dB).
High-Precision Calibration for Angle Measurement (σA, σE ≤0.015°, △A, △E ≤0.016°)
