ABSTRACT:
The invention pertains to a hand-held or vehicle mountable portable procer based high resolution radar system for detecting and identifying an object by using high resolution radar. In particular, the invention concerns using radio waves for identifying a depth and material of an object within a media. This system can perform target and media identification in real-time. This process is achieved by the system's processor where the media identification results can be visually displayed on an output unit. The generated carrier signal used in the radar 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 (A/D) conversion using integrated circuitry whose sampling rate is in the same as the carrier signal transmission rate. In addition, Fourier and Hilbert transforms of the observed signal is generated for frequency domain analysis of the observed object to be identified and a profile inversion methodology for real time analysis. To achieve high resolution results, digital codes such as Barker, Welti, or Frank codes are used in the processor. The carrier signal is coded using a digitally controlled phase shifter. Power usage by the instant invention's radar system is low. The profile inversion methodology is a real time based analysis.
