High Resolution Radar Range Tracking System.
Abstract
The patent application describes a radar tracking system using linear frequency ramps. A first frequency generator produces a linearly rising signal for a predetermined time that is transmitted and received and mixed with a second signal initiated at a predetermined time, the second signal having the same ramp slope but offset in frequency by a known value. The resulting intermediate frequency signal is fed to a bank of bandpass filters, then to a bank of diode detectors, followed by a bank of sample and hold and threhold circuits. The threshold circuits are fed to the nearest range detector and the particular activated threshold circuit causes the detector to generate a range error work accordingly that is fed to a computer resulting in a range gate signal that initiates the second frequency ramp signal.
