Abstract. This study focuses on the determination and validation of a new global mean sea surface (MSS) model, named Shandong University Science Technology 2020 (SDUST2020), with grid size 1?×1?. model was established 19-year moving average method fused multi-satellite altimetry data over 27-year period (from January 1993 to December 2019). The HaiYang-2A, Jason-3, Sentinel-3A were first ingest...

We call a $4$-cycle in $K_{n_{1}, n_{2}, n_{3}}$ multipartite (denoted by $C_{4}^{\text{multi}}$) if it contains at least one vertex each part of . The Turán number $ C_{4}^{\text{multi}})$ and $\{C_{3}, C_{4}^{\text{multi}}\})$ is determined the paper as well anti-Ramsey $\text{ar}(K_{n_{1},n_{2},n_{3}}, C_{4}^{\text{multi}})$. prove that $\text{ex}(K_{n_{1},n_{2},n_{3}}, C_{4}^{\text{multi}})...

A method for direction of arrival (DOA) estimation and object localization based on 1-bit time-modulated reflectarray (TMRA) is presented. The multi-harmonic multi-beam (MHMB) characteristic TMRA analyzed firstly to reveal the mapping relationship between target’s angular feature received spectrum feature. Then operating principle perception procedures single multiple targets scenarios are disc...
