Practical Analysis of Radar Interference in a Communications System

Increase in the heavy usage of wireless network and radar systems have urged the need for efficient spectrum sharing. Technical parameters for both the system are limited by the spectrum allocations, hence this research addresses this issue by presenting the novel experimental model to understand S-Band (from 2 GHz to 4 GHz) radar interference in an uncoded communications system. This real-time model was developed using Keysight signal analyzer and signal generator. Consequently, a number of parameters were varied and test cases were evaluated, especially bit-error-rate performance to underline the appropriate requirement for radar to coexist with the communications system. The adopted method was also compared with the ideal cases and verified with a brief theoretical analysis.
