Accuracy detecting system of 3-dimensional (3D) product produced based on onboard interferometric synthetic aperture radar (INSAR)

The utility model discloses an accuracy detecting system of a 3-dimensional (3D) product produced based on an onboard interferometric synthetic aperture radar (INSAR). The system comprises a parameter inputting unit used for inputting tolerance, an actual measurement data transmitting device used for inputting three-dimensional space coordinate data of a plurality of actual measurement points actually measured outdoors, a detection data transmitting device used for inputting the 3D product to be detected and a data processor used for analyzing and processing data input by the actual measurement data transmitting device and the detection data transmitting device and correspondingly acquiring height errors of a plurality of detection points in the 3D product and corresponding to the plurality of actual measurement points and plane position errors. The 3D product comprises a digital line graphic (DLG), a digital evaluation model (DEM) and a digital orthophoto map (DOM) which are produced by an onboard interferom
