The present invention provides a method for optimizing the beam position design of a spaceborne SAR. Different from the previous idea of ​​using a fixed pulse width as input for all beam positions, the pulse width is designed and output for different beam positions; different from the problem that the previous design has no automatic iteration capability or the iteration method is simple, the automatic iteration function of the design is realized through a three-layer loop iteration step-by-step parameter adjustment method. Beneficial effects of the present invention: the pulse width is designed for different beam positions, instead of using a fixed and unique pulse width as input for all beam positions, which not only avoids the situation that some beam positions have harsh timing constraints due to excessively wide pulse widths, and thus the designable PRF range is too small or non-existent, but also avoids the situation that some beam positions have poor noise equivalent backscatter coefficients due to excessively narrow pulse widths, thus affecting the design results, effectively improving the flexibility of the design and the performance of the design results; at the same time, the design capability of the system is improved and the optimal design results are ensured.
