Description: Technical Report
Abstract: This report describes a hand-held or vehicle-mountable, portable processor based, high-resolution radar system for detecting and identifying an object using high-resolution radar techniques. In particular, the system uses radio waves for identifying a depth and material of an object within a medium. This system can perform target and media identification in real-time. This is achieved by the system's processor where the media identification results can be visually displayed in an output unit. The generated carrier signal used in the system is an exponentially decaying superimposed direct and alternating signal. The frequency of the carrier signal can be in the microwave region. The system performs analog-to-digital (AID) conversion using integrated circuitry. In addition, Fourier and Hilbert transforms of the observed signal are generated for frequency demain analysis, and proflle inversion methodology is applied in this system. To achieve high-resolution results, digital codes sucb as Barker code or Welti codes are used in the processor. The carrier signal is coded using a digitally controlled phase shifter. Power usage by this radar system is low.
