Abstract
Introduction/purpose: The OTHR simulator presented in this paper is developed and used in practice, with the aim of emulating radar signal environment, but also optimizing the radar parameters in real applications such as: radiated power, antenna array gain, path loss, radar cross section, external interference, and noises. Methods: In this paper, the methodology of mathematical modeling is used as well as simulations . Results: Based on the performed analysis, the output data from the OTHR simulator is presented and discussed. Conclusion: The usage of the presented OTHR simulator makes assessing the reliability of a potential radar at predetermined locations automated, controllable and efficient, with results closely matching radar behavior in real operation.
Highlights
The Over The Horizon Radar (OTHR) simulator presented in this paper is developed and designed in order to predict and analyze all external parameters that affect the OTHR functionality
While the detection and tracking concept used in our research is already explained in detail, along with communication and data management for OTHR systems (Petrovic et al, 2020), in this paper we focus on describing the modeling process itself, which is the core of the Simulator and a true basis for all other features resulting from it
We presented a solution for the OTHR Simulator, based on software models for radar propagation and executed on a standard COTS computer
Summary
We presented a solution for the OTHR Simulator, based on software models for radar propagation and executed on a standard COTS computer. The solution is described in detail, and tested under characteristic parameters that verify its basic functionality and illustrate the properties of data achieved through the simulation. The Simulator solution was tested under various scenarios, with the aim to check its basic functionality, and to make relevant comparisons of simulations with realistic measurements acquired in the field, from operational OTHR radars. As it was clearly shown, the achieved simulation results apply to the expected theoretical behavior, and fit in quite a reasonable manner with the real data, confirming that the reliability of the simulations is at the level properly high for practical considerations. The described software solution can be used for research & development of radar systems, or for commercial applications strictly, and for teaching purposes at higher education institutions which are covering the field of radar systems
