Abstract
In this chapter, we propose a novel way to combine back projection and trilateration algorithms for through-the-wall imaging using an ultra-wideband (UWB) short-pulse radar system. The combination of the two algorithms increases the detection-localization performance. To accomplish this improvement, the multi-target localization problem of trilateration is addressed by the calculation of the root-mean-square error with regard to the estimated position and those of all possible target positions. The radar system’s entire processing pipeline is described, with a focus on the imaging block. The data were acquired using a multistatic radar system with a 3.2 GHz bandwidth. Simulations and experiments indicate that our combined method outperforms other methods. Simulation and experimental results are shown, compared, and discussed.
