One of the most important purposes of a validation method is to verify whether a test method is suitable for the purpose of the test. In this study, validation parameters that are used by national and international institutes for test and inspection bodies are classified. As a result of classifying these general factors, method validation parameters were performed, including the following cases: ① the confirmation of a new test method, ② comparison between a non-standardized test method and standardized method, ③confirmation of a test method needing such extensions as a test method verification, verification of the test method applied between other test institutes or analysts, ④ verification of the required similarity between test methods, and ⑤ revalidation of the previously verified test methods. The general parameters applied in the validation processes were classified as follows; specificity, selectivity, linearity, sensitivity, accuracy, precision, detection limit uncertainty, quantitative limit, and range. By a comparison of the validation guidelines or guideline parameters applied by the test and inspection bodies, the survey results were considered to be useful in preparing validation guidelines for environmental testing and inspection methods.

In this paper, we survey the Moving Target Indication(MTI) techniques for small UAVs. MTI consists of image alignment phase and frame differencing correction phase, and image alignment has two ways of parametric approach which is mainly focused in this paper and non-parametric approach. Since small UAVs are operated in the low altitude, the parallax is considerable and the epipolar geometry is applied to compensate the parallax. The related works and future works are presented.
