Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
An autofocusing technique is proposed, based on the modelling of the instantaneous phase, induced by the relative radar/target motion, as a generic order polynomial and on the estimation of the polynomial coefficients by the so-called product high-order ambiguity function. The proposed estimation method is able to deal with multicomponent signals and is robust against model order mismatching, provided that the selected order is greater than the true order. The proposed method is compared with the phase gradient autofocusing method, and applications are presented of focusing of extended scenes and detection and imaging of moving targets. © lEE, 1998.
