Analysis of Mutual Coupling Models for Phased Array Calibration
(2022-05-13)
There is a demand for more effective phased array calibration both in initial and in
situ setups, including but not limited to airborne and spaceborne radars. Mutual coupling is a method of calibration which involves ...
Nonlinear Amplifier Amplitude Modulation Distortion Mitigation Techniques
(2022-05-13)
High peak-to-average power ratio (PAPR) waveforms present a challenge to
radar systems in which high power amplifiers operate in saturation to increase
power efficiency. Previous works have demonstrated a marked reduction ...
A New Front-End System For UAV-Based Antenna Measurements For Polarimetric Weather Radars
(2023-08-04)
