Patent number: 11747434Abstract: Detection of a radar target from a received radar signal includes computing a vector of filter weights dependent upon a steering vector and determining a threshold value dependent upon a designated probability of false alarm. The vector of filter weights is applied to samples of the received radar signal at a test cell, corresponding to a test range, to provide a filtered test signal and a test power of the filtered test signal is computed. The weights are also applied to samples of the received radar signal at a number of reference cells, to produce filtered reference signals. A reference power is computed from the filtered reference signals and the radar target is detected at the test range when a ratio of the test power to the reference power exceeds the threshold value.Type: GrantFiled: March 24, 2021Date of Patent: September 5, 2023Assignee: United States of America as represented by the Secretary of the Air ForceInventor: Ramachandran S.

Patent number: 11738322Abstract: The present invention relates to a microfluidic flow process for making polymers, polymers made by such processes, and methods of using such polymers. In such process, a novel reagent delivery setup is used in conjunction with microfluidic reaction technology to synthesize anionic polymerization reaction products from superheated monomer orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does not require the cryogenic temperatures which are required for such syntheses in batch or bulk continuous. Thus the aforementioned process is more economically efficient and reduces the environmental impact of linear polymer production.Type: GrantFiled: March 31, 2021Date of Patent: August 29, 2023Assignee: United States of America as represented by the Secretary of the Air ForceInventors: Kamran B.
