ACCELERATION AND VELOCITY PROCESSING OF HF RADAR SIGNALS
Abstract
When determining the design of the signal processor, the overall radar problem must be considered in order to achieve optimum radar performance. The choice of a signal processor type for a high-frequency, over-the-horizon, pulse-doppler radar is particularly important because it must perform maximum signal enhancement to detect and observe very small signals buried in noise and, simultaneously, extract the maximum target information. Although many factors influence the design, this report is primarily concerned with the effect of target acceleration on the performance of the signal processor. Since targets of interest include guided missiles as well as aircraft, provision for acceleration and velocity processing should be included to insure that maximum sensitivity and velocity resolution will be available for both accelerating and constant velocity targets. Examination was made of how target acceleration degrades performance in a simple velocity analyzer and also the method of providing essentially maximum sensitivity and velocity resolution for accelerating targets by an acceleration processing technique of spectral compression. Actual results obtained with a limited, 12-acceleration gate, acceleration and velocity signal processor confirm that full system sensitivity and velocity resolution are provided for accelerating and constant velocity targets.
