摘要：

In this study, a spectrum sharing technique is investigated for enhanced detection of moving targets. This approach, the spectrum sensing-multi-objective optimisation technique, passively monitors the electromagnetic environment for radio frequency (RF) emissions radiated by RF systems. This technique then identifies a continuous frequency sub-band that simultaneously maximises radar performance and reduces the radars spectral footprint. The goal of the investigation presented in this study is to quantify performance improvement of a notional radar model in the presence of RF emissions measured at 2.42GHz (by a real-time spectrum analyser). In addition to an improved signal-to-interference plus noise ratio, the proposed radar model increases range resolution performance as the target approaches the radar.
