This Small Business Innovation Research (SBIR) Phase I project will investigate beam steered electromagnetic radar using differential synchronization signal path switching (DSSPS) to increase the operable frequency and target resolution. The research will also determine the effective imaging beam refraction as it exits opaque media, the feasibility of classifying human targets in the downrange profile, and the feasibility of implementing fractal geometries into bow-tie antennas to reduce ringing. Phase I will result in a compact system capable of penetrating thick opaque materials using high frequencies to locate targets in an arena that is otherwise reserved for low frequencies because of attenuation and the steering limitations of electronic delay methods.Potential commercial applications are expected in electromagnetic application for subsurface feature detection, including voids, contaminants, hazardous waste containers, hydrologic-lithologic interfaces, the location of buried utilities, and for locating human targets through opaque materials such as buildings, earth, rock, and snow. The smaller size of a high frequency array offers portability for the latter application.

这个小企业创新研究（SBIR）第一阶段项目将研究使用差分同步信号路径切换（DSSPS）来提高可操作频率和目标分辨率的波束操纵电磁雷达。 这项研究还将确定有效的成像光束折射，因为它退出不透明的介质，分类人类目标的可行性在downrange配置文件，并实施分形几何到蝴蝶结天线，以减少振铃的可行性。 第一阶段将产生一个紧凑的系统，能够使用高频穿透厚的不透明材料，以定位竞技场中的目标，否则该竞技场由于电子延迟方法的衰减和转向限制而被保留用于低频。地下设施的位置，并通过不透明的材料，如建筑物，泥土，岩石和雪来定位人类目标。 高频阵列的较小尺寸为后一种应用提供了便携性。
