Summary:
A method for broadband active imaging using the autocorrelation pulse (ACP) response is proposed to realize a low cost real-time imaging system constructed by power detector array. In this method, swept continuous waves in a broad frequency range are transmitted to the scatterer and the received power spectrum obtained by means of the squared detection of scattered waves is transformed into ACP response by using the Inverse Fourier Transformation (IFT). Then ACP response is used for the imaging of objects. ACP response can be obtained by using only the magnitude of scattered waves, but it includes non-physical (false) response. It is shown theoretically and experimentally that a strong couple between the transmitting and receiving antennas yield the reduction of the false pulses.
