AstroSoft company with participation of Prognoz Research institute is conducting investigations on algorithmic software for radar data processing creation, supposed to be a part of radar control software. Also, software suite for radar functioning in the given target en-vironment simulation (hereinafter - simulation software suite) is under development. The algorithmic software includes radar signal processing algorithms and object tracking algorithms as its parts. At the current stage of the investigations, computer simulations are carried out to acknowledge the algorithms functional capabilities. The algorithmic software is then supposed to be tested and debugged at the real radar complex at the next stage. Among the various known methods of radar signal processing, mathematical apparatus of statistical hypothesis comparison was used to reduce the amount of unsuppressed radar flashes originated from interferences. Thus, the optimized algorithms showed a good result when tested at the different target environment mathematical and computer models. The output of object tracking algorithms are the objects tracks at the plan-position indicator display. Performance tests on the algorithms developed were also made with the use of target environment mathematical and computer models, according to the scenarios described in the IEC 62388 international standard, «Maritime navigation and radiocommunication equipment and systems - Shipborne radar - Performance requirements, methods of testing and required test results». The simulation software suite is designated to supplement tests in situ by simulation modeling results. The need for this kind of software is caused by the high cost and complexity of experimental tests for performance verifications. There are, roughly, three main options for building the simulation software suite (or, in general, simulation hardware and software suite): the first option is building, namely, simulation software suite allowing to carry out tests on only radar algorithmic software by feeding it with the target environment information and verifying computation results; the further extension is adding intermediate frequency generator which would allow to test radar computing unit, including its hardware and software; the largest set of equipment includes also antenna unit to emulate microwave reflected signal, thus allowing to carry out tests on the radar complex as a whole. By now, AstroSoft efforts are close to completion on the simulation software suite development (the first option). It is also planned further suite evolution up to the second option.
