[0117] This part uses the actual ISAR system to test the imaging of the International Space Station (ISS) to verify the validity of the system parameter design method proposed by the present invention. First, according to the input parameter table provided in Table 1 and the orbital information of the International Space Station announced by the North American Aerospace Defense Command, according to the method proposed by the present invention, the parameters required for ISAR imaging are calculated, and the results are shown in Table 2. Then set the radar antenna mechanical scanning and electrical scanning angles according to the obtained parameters, set the ISAR system working status and imaging time, and estimate the expected imaging results. Finally, when the International Space Station passes through the area covered by the radar beam, it starts imaging and obtains the final test ISAR image.
