Transmit Beamspace Design for Bistatic MIMO Radar With Improved Angle Estimation
IEEE Access, 2019 The energy dispersion of traditional bistatic multiple-input multiple-output (MIMO) radar severely degrades the angle estimation performance. To overcome this limitation, we propose to design the transmit beamspace matrix and apply the design result to ...

A Novel Sparse Framework for Angle and Frequency Estimation
Sensors, 2022 The topic of joint angle and frequency estimation (JAFE) has aroused extensive interests in the past decades. Current estimation algorithms mainly rely on the Nyquist sampling criterion. In order not to cause ambiguity for parameter estimation, the space–

Load angle estimation of synchronous generator [PDF]
Zbornik radova Elektrotehnicki institut Nikola Tesla, 2020 In this paper a load angle estimation method of round rotor synchronous generator is presented, for load angle limiter in AVR systems design purpose. To get information of load angle, it is necessary to have values of the one terminal voltage, one phase current and q-axis reactance Xq. Mentioned values are acquired by synchronous sampling technique and

RADARSAT ScanSAR roll angle estimation [PDF]
IEEE International Geoscience and Remote Sensing Symposium, 2003 Wide-swath SAR imagery obtained by the RADARSAT ScanSAR mode can suffer from radiometric artifacts. These artifacts arise from improper application of Range Dependent Gain Corrections (RDGCs), mainly due to insufficient knowledge of the satellite's roll angle.

Iterative roll angle estimation from dense disparity map [PDF]
, 2018 The v-disparity map is predominantly used to estimate the parameters of the vertical profile of the road surface. Once the road surface is modelled, an object that lies away from it can be detected and determined as either an obstacle or a pothole.
