A triple-frequency CW radar system for mutable-range distance measurements

A particular problem that should be addressed in the radar sensors is how to measure the distances of stationary, slow-moving and fast-moving targets such as vehicles precisely and rapidly. This paper describes a new approach to measure distances between objects using triple-frequency CW (Continuous Waveforms) Radar and based on a K-band Doppler technology. The system's operation is performed using CW triple-frequency to obtain expeditiously and highly accurate measurements for stationary and moving objects. 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 model.
