Designing sequence set with minimal peak side-lobe level for applications in high resolution RADAR imaging

no code implementations7 Sep 2020 Surya Prakash Sankuru, R Jyothi, Prabhu Babu, Mohammad Alaee-Kerahroodi

Constant modulus sequence set with low peak side-lobe level is a necessity for enhancing the performance of modern active sensing systems like Multiple Input Multiple Output (MIMO) RADARs.

Reconfigurable and Intelligent Ultra-Wideband Angular Sensing: Prototype Design and Validation

no code implementations13 Aug 2020 Himani Joshi, Sumit J. Darak, Mohammad Alaee-Kerahroodi, Bhavani Shankar Mysore Rama Rao

The emergence of beyond-licensed spectrum sharing in FR1 (0. 45-6 GHz) and FR2 (24 - 52 GHz) along with the multi-antenna narrow-beam based directional transmissions demand a wideband spectrum sensing in temporal as well as spatial domains.
