An apparatus and method for remote detection and monitoring of concealed objects are disclosed. According to one embodiment, an apparatus includes one or more transmitting antennae, one or more receiving antennae with a plurality of receiving channels, a pulse sequence generator providing a sequence of pulse signals to the one or more transmitting antennae, and a signal processing unit receiving a sequence of return signals from an object reflecting the sequence of pulse signals. The signal processing unit includes a variable delay generator that receives signal profile of the sequence of pulse signals from the pulse sequence generator, an amplifier that amplifies the sequence of return signals, a multi-channel integrator that integrates the plurality of receiving channels and produces integrated multi-channel signals, and an analog multiplexer that multiplexes the integrated multi-channel signals. |
