Embodiment Construction
[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0062] The invention provides a high-resolution radar scatterometer for scanning beams. At the same time, the invention proposes a technical solution combining beam conical scanning and high-resolution processing to meet the observation requirements of both wide swath and high resolution. The radar scatterometer uses a beam rotating scanning antenna, such as figure 2 As shown, it includes: an antenna unit, a transmitter unit, a receiver unit, a digital processing and control unit, a Doppler sharpening processing unit and a high-resolution processing unit; the antenna unit adopts a narrow beam conical scanning system for realizing Rotate the pencil beam to scan, the transmitter unit generates and transmits a chirp signal, and when transmitting the chirp signal, it corresponds to an observation azimuth The receiver unit receives the pulse signal and performs...
