Use of cluster analysis method to increase the efficiency and accuracy of radar data processing

The article presents a range of solutions to improve the efficiency and accuracy of multiradar data processing using cluster analysis method. For this purpose commend to use cluster analysis method, based on which authors made an improvement for the classical abnormal measurement rejection algorithm and consider a possibility to implement a multithread processing of radar data.

About the precalculation of the accuracy of building geodetic nets

The construction of geodetic construction nets is traditionally produced according to the deductive principle of the transition from the general to the particular. As noted in [1], each previous step should create a reliable control of the construction of the subsequent one and do not affect in a tangible way the accuracy of determining the points of the newly constructed grid.
