Analysis of stroboscopic signal sampling for radar target detectors and range finders

This study considers the influence of signal sampling on the characteristics of target detectors and range finders, which form parts of radar systems. Quasi-optimal algorithms for target detection and range measurement are analysed, which demonstrate close to optimal performance even if low-performance signal processing equipment is used. Special attention is given to stroboscopic sampling. In the case of a high signal-to-noise ratio, stroboscopic sampling can provide better detection performance than traditional, or real-time, sampling. The accuracy of range finders with stroboscopic signal sampling is estimated. The considered method allows for a reduction in both instrumental range measurement error and random error of tracking compared with traditional sampling methods, without an increase in requirements of the range finders´ performance.
