The sample support problem in space-time adaptive processing (STAP arises from the requirement to adapt to a changing interference environment where the available wide-sense-stationary sample support is severely limited for direct implementation ofadaptive algorithms. In this proposal by combining several approaches such as (i) forward/backward subaperture-subarray smoothing techniques (ii) alter ...

The sample support problem in space-time adaptive processing (STAP) applicationsarises from the requirement to adapt many spatial and temporal degrees-of-freedom (DOF) to a changing interference environment that includes clutter and jammers. Often, in heterogeneous overland strong clutter environments, the available wide sensestationary sample support is severely limited to preclude the direct imp ...

Based on the previous extensive work on NIL in Prof. Chou's group and at Nanonex Corporation, the objective of the project is to further develop a promising innovative nanoimprint lithography (NIL) machine design. The design, using a new principle, offersnot only excellent uniformity of nanostructures over large areas, high-throughput (

The project has the objective of studying the feasibility of a number of novel methods and concepts for electric power generation for high-speed guided gun-launched interceptors and other similar projectiles. A number of the electrical power generationconcepts are integrated into the structure of the projectile. As the result, all or a significant portion of the space required to house an equivale ...

We propose to improve and fully develop the innovative cost-effective SiC process technology demonstrated in Phase I to fabricate and commercialize a novel SiC vertical JFET (VJFET) whose feasibility has been firmly demonstrated in Phase I. The innovativeprocess technology and the novel SiC VJFET device structure will make it possible (I) to reduce the high power dissipation of SiC devices from th ...

Based on the successful Phase I development of a SiC inverter for motor control in Phase I, we propose to perform the major R&D work in Phase II and commercialization development in Phase III for an all-SiC inverter capable of high temperature, high powerand high speed control of three phase ac induction motors. In Phase II, we shall increase the inverter power by a factor of 10, increase the PWM ...
