Embodiment Construction
[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0039] A spaceborne SAR real-time imaging device, such as figure 1 As shown, it includes a satellite attitude orbit control unit, a central processing unit, a SAR payload, a SAR imaging processing unit, an intelligent information processing unit, a data processing unit, and a payload control unit. The above modules cooperate to complete the satellite SAR imaging task. like figure 2 As shown, the task flow is set to firstly carry out low-resolution wide-area census SAR imaging of frontal and side-looking strips, and conduct preliminary detection of the target of interest on the obtained SAR images, and organize the rear squint spotlight height according to the detection results and satellite-related information. Check the resolution of SAR imaging in detail, and perform interest target detection, slice extraction, and target identification based on deep l...
