[0002] The interferometric imaging altimeter is a new type of radar altimeter that uses techniques such as small incident angles and short baseline interferometry to measure sea surface height over a wide area. This enables high-efficiency, high-spatial-resolution, and high-precision detection of sea surface height in dynamic ocean environments. To date, the only interferometric imaging altimeters successfully launched and operational internationally are the Ku-band three-dimensional imaging microwave altimeter aboard my country's Tiangong-2 spacecraft and the Ka-band interferometric radar instrument (KaRIn) aboard the US SWOT (Surface Water and Ocean Topography) satellite. Subsequent interferometric imaging altimeter missions are gradually moving toward the KuKa dual-frequency approach. The KuKa dual-frequency interferometric imaging altimeter's unique pulse burst operating mode and timing require the KuKa dual-frequency multi-beam antenna to quickly and accurately change beam pointing to accommodate wide-area sea surface observations. This also places high demands on user-side beam control, necessitating the design of a dedicated user-side beam control system specifically tailored to the KuKa dual-frequency multi-beam antenna's control.
