Investigation of the Reliability of the On-board Radar Complex Taking into Account the Influence of Dissimilar Physical Factors

Currently, there is an active exploration and exploration of space and near-Earth space with used radar systems and complexes. Scientists and engineers are faced with the tasks of defense, scientific, technical and economic nature. The Meteor-3M space complex has been developed since 2006, Within the framework of the Federal Space Program of Russia. Roskosmos and Roshydromet are customers of this project. A high level of reliability is necessary, since this airborne radar complex belongs to the group of 5.1 instruments. The calculation of the reliability of the automation unit of the on-board radar complex of the spacecraft Meteor-M No. 3 was carried out in the program ASONIKA 6.3 with the purpose of verifying compliance of the established TK reliability requirements. The sets of units and the requirements for the assignments of the electronic modules included in the on-board radar complex are described in the work. Also, the structural diagrams are given in the report. The calculation of failure-free performance was carried out in ASONIKA-B and the calculation of thermal-mechanical effects in ASONIKA-TM.
