SUMMARY:

• Over 16 years of signal processing and data analysis with a strong proficiency in developing algorithms with an emphasis in radar systems, RF systems, communication systems, cognitive radio, Software Defined Radio, satellites remote sensing, atmospheric modeling, and cybersecurity, (Cyber Electronic warefare (EW)).
• Systems and methods for sensing targets on an opposite side of a wall are disclosed. In some aspects, the techniques include providing an indication to a user that portions of reflected radar signals were blocked by radiofrequency - blocking material at the wall. In some aspects, the techniques include identifying candidate targets as multipath echoes or motion-induced errors based on a correlation map
• A device includes a radar system configured to be placed in a hiding mechanism, the radar system having one or more transmit antennas oriented within the hiding mechanism and configured to transmit one or more radar signals toward a barrier, one or more receive antennas oriented within the hiding mechanism and configured to receive reflection signals of the transmitted radar signal back through the barrier and back through the hiding mechanism, one or more transceivers coupled to the one or more transmit antennas and the one or more receive antennas, and an electronic processor to analyze the received reflection signals of the transmitted one or more radar signals, and determine, based on the analyzed received reflection signals, locations of the one or more individuals within a region at a side of the barrier.
