Global optimization or maximum-correlation-based algorithms have been used to realize range alignment. However, it is still challenging to achieve range alignment in low signal-to-noise ratio scenarios, which are common in inverse synthetic aperture radar imaging. In this paper, a novel anti-noise range alignment approach is proposed. In this new method, the target motion is modeled as a uniformly accelerated motion during a short sub-aperture time. Minimum entropy optimization is implemented to estimate the motion parameters in each sub-aperture. These estimated parameters can be used to align the profiles of the current sub-aperture. Once the range profiles of each sub-aperture are aligned, the non-coherent accumulation gain is obtained by averaging all profiles in each sub-aperture, which can be used as valuable information. The accumulation and correlation method is applied to align the average range profiles of each sub-aperture because the former step focuses mainly on alignment within the sub-apertures. Experimental results based on simulated and real measured data demonstrate the effectiveness of the proposed algorithm in low signal-to-noise ratio scenarios.<\/jats:p>","DOI":"10.1186\/s13634-020-00709-z","type":"journal-article","created":{"date-parts":[[2021,1,11]],"date-time":"2021-01-11T07:19:19Z","timestamp":1610349559000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Noise-robust range alignment method for inverse synthetic aperture radar based on aperture segmentation and average range profile correlation"],"prefix":"10.1186","volume":"2021","author":[{"given":"Yue","family":"Lu","sequence":"first","affiliation":[]},{"given":"Jian","family":"Yang","sequence":"additional","affiliation":[]},{"given":"Yue","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Shiyou","family":"Xu","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,1,11]]},"reference":[{"issue":"1","key":"709_CR1","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1109\/TAES.1980.308873","volume":"AES-16","author":"C. -C.
