Embodiment
[0036] In order to illustrate the effectiveness of the present invention, verification experiments such as a single control point and a simulation terrain are performed. The simulation parameters of the example are shown in Table 1, and Table 2 gives three different methods (including: None based on the maximum timing. Constrained search method, maximum cycle graph method, PS-INSAR precise search based on maximum periodic map) Estimates comparison results of single control point elevation and variable rate time consumption and accuracy, showing the above three methods estimated simulation terrain elevation Comparison of the relative accuracy of the variable rate, figure 2 A SAR image of the simulation terrain and the simulation terrain elevation map are given. image 3 and Figure 4 Reconstructing results are given separately.
