[0002] Interferometric imaging altimeters are a new type of radar altimeter that employs techniques such as small incident angles and short baseline interferometry to achieve wide-area sea surface height measurement. They meet the requirements for high-efficiency, high spatial resolution, and high-precision detection of sea surface height in marine dynamic environments. To date, only the Ku-band three-dimensional imaging microwave altimeter aboard my country's Tiangong-2 space station and the Ka-band interferometric radar instrument (KaRIn) on the US SWOT (Surface Water and Ocean Topography) satellite have been successfully launched and are operating in orbit. Subsequent interferometric imaging altimeter missions have gradually shifted towards KuKa dual-frequency systems. The unique pulse cluster operating mode and timing of the KuKa dual-frequency interferometric imaging altimeter require the KuKa dual-frequency multi-beam antenna to be able to quickly and accurately change beam pointing to adapt to the needs of wide-area sea surface observation.

[0054] Example

[0055] like Figure 1As shown, an embodiment of the present invention provides a user-end beam control system for a KuKa dual-band multi-beam antenna. This beam control system receives operating commands for the KuKa dual-band multi-beam antenna transmitted by the payload synthesis electronics, parses and judges them, and then sends them to the KuKa dual-band multi-beam antenna for execution.

[0077] The telemetry data packet unit integrates the Ku telemetry information frames and the Ka telemetry information frames and transmits them to the serial communication unit.

[0078] In one embodiment, the serial communication unit mainly implements a serial transceiver communication protocol.
