摘要
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.
