Acquisition, Doppler Tracking, and Positioning With Starlink LEO Satellites: First Results

IEEE Transactions on Aerospace and Electronic Systems, 2022
This letter shows the first acquisition, Doppler tracking, and positioning results with Starlink's low Earth orbit satellite signals. A generalized-likelihood-ratio-based test is proposed to acquire Starlink's downlink signals.

Deep Learning for Classification of Mini-UAVs Using Micro-Doppler Spectrograms in Cognitive Radar

IEEE Aerospace and Electronic Systems Magazine, 2019
Military radar can not only provide kinematic information (position, speed, and course) of land, sea, and air targets during day and night in all weather conditions, but also provides information about the type of target using micro Doppler properties ...
