15th Order M-sequence SoC Radar for Short-Range Sensing

This paper deals with the description and evaluation of the M-sequence UWB radar system on chip (SoC). Instead of common 9th or 12th order M-sequence generator, the proposed UWB radar includes the 15th order generator. Therefore, it has significantly longer unambiguous range and is able to exploit the regulatory spectral masks more efficiently. Consequently, it is better suited for sensing applications which require longer range and small dimensions of radar system. The theoretical assumptions are confirmed by experimental measurements in a simple measurement scenario.
