Abstract

A serial scan thermal imaging system with a multielement matrix type detector is discussed. The parallel TDI signals are converted into a serial signal by using CCD delay lines in the system. By this process, high horizontal scan efficiency is realized, and the configuration of the high rotating scanner is miniaturized. In the system NETD depends on the scanning parameters, so scanning method satisfying simultaneously the requirements that NETD should be decreased and horizontal scanner should be miniaturized is discussed. On the other hand, ability of a target recognition by a thermal imaging system is frequently described by MRTD. Optimization of MRTD is also discussed and the optimum MRTD is obtained when the product of IFOV and a target spatial frequency is equal to 0.5 (cycle) . Finally the concrete system design adapted to midrange (order of a few kilometer) vehicle size target and some results of the performance evaluation of a prototype system manufactured are presented.
