The micro-Doppler (m-D) effect caused by the rotational parts of targets influences quality inverse synthetic aperture radar (ISAR) imaging. In this letter, a novel deep network-assisted method is proposed to reduce m-D in ISAR training data, including images with and without effect, help network establish non-linear mapping relationships. simulated measured data results show effectiveness meth...

Traditionally a rigorous mathematical document consists of a sequence of definition – statement – proof. Taking this basic outline as starting point we investigate how these three categories of text can be represented adequately in the formal language of Isabelle/Isar. Proofs represented in human-readable form have been the initial motivation of Isar language design 10 years ago. The principles...

II We have designed and developed an automatic ship classification (ASe) system for classifying potential naval targets from inverse synthetic-aperture radar (ISAR) imagery. Initially, the ASC system was developed for an over-thehorizon targeting application. In the application, an airborne platform with an on-board ISAR sensor transmitted imagery to a host ship carrying the ASC system. Our pre...

This paper presents a methodology for high resolution radar image generation and automatic target recognition emphasizing the computational cost involved in the process. In order to obtain focused inverse synthetic aperture radar (ISAR) images certain signal processing algorithms must be applied to the information sensed by the radar. From actual data collected by radar the stages and algorithm...

در این کار پژوهشی، نمونه‌های هیدروکسی اپتایت آلاییده با ناخالصی‌های سریم، گادولونیم و ترکیبی از دو ناخالصی به روش هیدروترمال سنتز شدند. منظور بررسی فازهای بلوری تشکیل یافته هرکدام شده، کد MAUD که یک نرم‌افزار برای تجزیه تحلیل ساختار ماده استفاده پراش بر اساس ریتولد است، شد. پاسخ دزیمتری ترمولومینسانس نمونه‌ها مورد قرار گرفت یافته‌ها نشان داد نمونه‌ ترکیبی، سطح میانی است. مشخص شد افزودن سریم می‌...

A novel RFID inverse synthetic aperture radar (ISAR)-synthetic (SAR) localization method is proposed and demonstrated which exploits reference tags with known locations to estimate the trajectory of a mobile platform locate target unknown locations. system that integrates robot an integrated reader antenna used obtain phase measurements both when moving along its trajectory. The ISAR algorithm ...

Air-to-sea surveillance and tracking systems that provide rapid and positive identification of Non-Cooperative and Stealthy Targets (NCSTs) are connected with Inverse Synthetic Aperture Radar (ISAR) concepts and techniques. ISAR has several shortcomings that could be dealt with the contribution of a Phase Comparison Monopulse system. This paper presents the possible output for the height dimens...

The utilization of global navigation satellite system (GNSS) signals for remote sensing has been a hot topic recently. In this article, the feasibility GNSS-based passive inverse synthetic aperture radar (P-ISAR) is analyzed. P-ISAR can generate two-dimensional image moving target, providing an estimation target size, which very important information in recognition. An effective imaging algorit...
