Synthetic-aperture radar based on nonsinusoidal functions. VIII Velocity and acceleration processing

The conventional radar using pulses and a sinusoidal carrier derives the range of the target from the pulses, and the velocity from the sinusoidal carrier; the two measurements are essentially independent of each other. A radar using pulses without a sinusoidal carrier measures only the range, but with a much higher accuracy if properly used, e.g., for a high-resolution all-weather radar using bandwidths of one to ten gigahertz. The velocity is obtained from two range measurements, the acceleration from three range measurements, etc. The processing differs strongly from the conventional Doppler processing. The required circuits would be very difficult to implement with the current technology, but the time lag between basic theory and practical implementation assures that our technology will have greatly advanced when the theory reaches the engineering level.
