Abstract

In this paper, we present a robust algorithm for demodulation and
evaluation of backscatter transponder induced beat signals in wireless
positioning systems. In particular, an analysis filter bank based on
Goertzel filter is used for signal detection. A particle swarm optimizer
controls the configuration of the filter bank and is used to measure
the range of the transponder based on spectral evaluation of the beat
signal with very high resolution. A Kalman-Filter is applied for optimum
estimation of the range with noise suppression. An implementation and
system demonstrator based on an heterogeneous FPGA and software
implementation with an FMCW radar is presented to evince the proposed
demodulation scheme. It allows gapless processing in chirp sequence
radar systems and high output rates with high resolution and low noise.
