Simulation of High Fidelity Foliage Penetration (FOPEN) at Ku Band

Synthetic aperture radar (SAR) systems use electromagnetic (EM) waveform transmissions to illuminate objects, and images are created from processing reflections or echoes. SAR systems are now widely deployed to support critical remote mapping/sensing capabilities. SAR transmitters are typically installed on moving airborne or satellite platforms to operate at stand-off ranges and collect terrain data measurements. The measured data, collected from multiple passes/scans is interpreted by advanced SAR interferometry algorithms into surface terrain maps to help discriminate (detect) key landscape features, e.g., fault lines, bodies of water, forests and vegetation, glaciers, etc. Some of the most technical tasks include discriminating foliage in mapped terrains, identifying forest types, discerning tree heights, and detecting anomalies or hidden objects beneath foliage - termed the foliage penetration (FOPEN) problem. Due to the increasing interest in using higher Ku-band frequencies (12-18 GHz) for FOPEN, there is a growing need to quantify the interaction of foliage with Ku-band frequencies for consulting purposes; and to aid with enhanced technology support for applications in both the commercial and military domains. Overall, this important area remains largely unaddressed in the modeling realm today because of the required heavy model detail and substantial computational resources. This technical paper lays out a FOPEN modeling methodology that introduces a range of new innovations and contributions to address the phenomenology of Ku-band EM wave transmissions through moderate foliage. Two highly detailed computer-aided design (CAD) tree models were created using an open source tree generating software. Due the level of details of tree models, Altair HyperMesh is used for geometry editing and cleaning and then Altair Feko is used for FOPEN computational electromagnetic (CEM) behaviors at L- and Ku-band are characterized.

Complex Radome Electromagnetics Simulation in Minutes

A radome is a structural enclosure that protects antennas and electronics from harsh weather and environmental factors without degrading electromagnetic signals to the radar. It is designed to have minimal impact on the electrical performance of the antenna and to withstand structural and wind loading performance requirements. They are used across multiple industries, including aerospace, defense, electronics, and telecommunications. Radomes, especially those containing multiple layers and curved FSS elements, are complex and the modeling and simulation of these systems can commonly take days and even weeks to complete. Altair’s streamlined radome simulation solution reduces this time to minutes. This webinar will overview Altair’s radome simulation solution and its application to design a radome system. Who Should Attend? This webinar has been designed to address the needs and challenges of engineering managers, EMC engineers, antenna engineers and designers, RF engineers, and Radio site engineers from military contractors (OEMs and their suppliers), defense governmental organizations (including navy, air force, army), and aerospace companies (OEMs and their suppliers).
