Abstract Based on the Minimum Spanning Tree （MST） method, we improved the searching algorithm for minimum closed loops in consideration of multiple connected graphs. A tree and some redundant branches are built up according to the nodes and the length of edges. The minimum spanning condition was satisfied by sequentially selecting the redundant branch which can construct the minimum loop. The independent condition was satisfied by keeping onetoone correspondence between the redundant branch and minimum loop. Finally, we applied the algorithm to detect InSAR phase unwrapping errors which greatly improved the efficiency of InSAR data processing.
