Software-Hardware Complex for Design, Full-Scale and Model Testing the Broadband Systems in Radio Communications, Radars and Navigation of High-Speed Objects

The development and the main technical characteristics of a software-hardware complex (SHC) intended for the design and field-model testing of broadband radio electronic systems (RES) for radio communication, radar, and navigation of high-speed objects are presented. The software-hardware complex provides generation and processing of signals with a carrier frequency of up to 6 GHz and a bandwidth of up to 200 MHz, a refresh rate of the channel impulse response up to 60 kHz, and a maximum rays delay in channel models up to 10 mu s. The complex allows one to study radio communication systems with objects that move with a relative speed difference of up to 5 M. The software part of the complex includes models of the signal formation and processing in the receiving and transmitting equipment of the radio electronic device, as well as models of radio channels for target scenarios of using the developed RES. The hardware part of the SHC is a set of digital, digital-to-analog, and analog-to-digital modules that allow full-scale and model testing of RES and their blocks in real time. Examples of studying the characteristics of a modern broadband aviation radio communication system with high-speed objects under conditions of signal multipath propagation are given. The application of the SHC may decrease the time of full-scale and model testing of RES by approximately 65 times compared to direct computer simulation.
