A minuscule distances' measurement using K-band Doppler technology

This paper discusses a new approach to measure very short distances between objects using two frequency Continuous waveforms and based on a K-band Doppler technology. The system's operation is performed using two-frequency radar to obtain expeditiously and highly accurate measurements for stationary and moving objects. Experiments have been conducted and a mathematical presentation of the system's model has been formulated along with computer-based simulations to study the performance and to validate the effectiveness of the proposed system's model. The obtained results demonstrate the capability of the system to adapt a short distance range.
