Abstract

The invention discloses an integrated technology for realizing the monitoring, control and real-time imaging processing of a multifunctional high-precision synthetic aperture radar system and an implementation method thereof. The technology disclosed by the invention can be applied to the processing and control of comprehensive data of the multifunctional high-precision synthetic aperture radar, namely, state information, parameters and data of various units of the radar system, including system working parameters, inertia, GPS (Global Positioning System) measurement data, radar echo data and the like, are acquired the acquired data information is subjected to integrated processing in accordance with the working mode of the system, and SAR (Synthetic Aperture Radar) real-time images and relevant processing results are generated while the processing results are utilized to perform optimized control and management on the system, thereby stable and reliable working of the high-precision multifunctional synthetic aperture radar is ensured.

Description

Technical field [0001] The invention belongs to the technical field of synthetic aperture radar (SAR) system control and data processing, and particularly relates to an integrated acquisition and processing of all states, information and data of a high-precision multifunctional synthetic aperture radar, and real-time acquisition of high-resolution radar images , And effective control and management of synthetic aperture radar. Background technique [0002] Synthetic Aperture Radar (SAR) is a high-resolution microwave imaging radar that can detect ground targets with high resolution and has the advantages of all-weather and all-weather. Since the emergence of aperture synthesis methods in the 1950s, SAR systems have been heavily loaded on flying platforms such as airplanes, satellites, and UAVs for the detection of ground targets. They are used in geographic resource surveys, crop monitoring, marine monitoring, It has been widely used in military reconnaissance and other fields. ...
