A nonparametric target shape estimation algorithm for UWB pulse radar systems

摘要

Environment measurement is an important issue for various applications including household robots. Radars utilizing ultra-wide-band (UWB) pulses are promising candidates in a near future. Estimating target shapes using waveform data, which we obtain by scanning an omni-directional antenna, is known as one of ill-posed inverse problems. Parametric methods such as Model-fitting method have problems concerning calculation time and stability. We propose a non-parametric algorithm for high-resolution estimation of target shapes in order to solve the problems of parametric algorithms.
