Reconfigurable Doppler radar using software defined radio platform for through-wall applications

A reconfigurable Doppler radar is implemented on a software defined radio platform for detecting humans behind walls. Two types of configurations are tested - a continuous wave radar and an orthogonal frequency division multiplex (OFDM) radar. Both the configurations yield micro-Doppler signatures while the OFDM radar gives additional range information. Measurement results of single and two humans are presented in through wall scenario.
