Abstract This work focuses on the optimal approach for implementing the reflected signal model in airborne radar systems. It primarily emphasises integrating various established and improved mathematical models for radar signals, terrains, and objects of different sizes, among others, to create an effective radar scene. Additionally, the unique features of the proposed models are briefly outlined. Furthermore, the algorithm for computing... This work focuses on the optimal approach for implementing the reflected signal model in airborne radar systems. It primarily emphasises integrating various established and improved mathematical models for radar signals, terrains, and objects of different sizes, among others, to create an effective radar scene. Additionally, the unique features of the proposed models are briefly outlined. Furthermore, the algorithm for computing radar echoes within the radar scene is examined. To wrap up, the necessary criteria for the models and recommendations are outlined. Read More Read Less

Abstract Modeling the clutter reflection suppression algorithm in synthetic-aperture radar is considered in the article. The proposed algorithm allows one to increase the signal detection eciency with closely located sources of clutter due to the use of a priori data of static objects of the infrastructure....

Abstract The research outlines the findings from a simulation of the close-range radiation region surrounding a ferrite antenna. It explains the HFSS model of the ferrite antenna, which includes a ferrite core, multiple wire coils, and a port for excitation. Additionally, the document displays the outcomes of estimating the antenna’s far-field boundary and visualizing the near-field elements. Conclusions were drawn regarding... The research outlines the findings from a simulation of the close-range radiation region surrounding a ferrite antenna. It explains the HFSS model of the ferrite antenna, which includes a ferrite core, multiple wire coils, and a port for excitation. Additionally, the document displays the outcomes of estimating the antenna’s far-field boundary and visualizing the near-field elements. Conclusions were drawn regarding the suitability of this setup of the ferrite magnetic antenna for ground-penetrating radar applications. Read More Read Less
