A Wide-Beam Scanning Mode for Near-Space Passive SARs
Figure 4
Simulation results of PRF bound with different receiver speed. Curved surface A: the upper bound of the PRF for near-space passive SAR. Curved surface B: the upper bound of the operational PRF range for the corresponding spaceborne illuminator. Curved surface C: the lower bound of the operational PRF range for the corresponding spaceborne illuminator. Curved surface D: the lower bound of the PRF for near-space passive SAR.
