Abstract

With the significant increase in mobile communications over the last decade, the communications bands have begun to encroach on the radar bands used by the military and other users. This includes the potential loss of some radar bands as well as sharing of the bands with other users which can result in degradation of both the communications and the radar performance. Techniques to mitigate this performance degradation will become increasingly vital in the coming years as the growth of wireless communication continues. This is especially critical in Europe where the wide-band 3G and 4G communications systems have allocated frequencies at 1800, 2100, and 2600 MHz. ISL s toolbox of RFI detection and mitigation techniques are based on the cognitive radar architecture. Adapted to existing systems, these techniques provide a capability to robustly detect low levels of RFI and adapt the radar waveform to minimize interference while maintain radar system performance.
