Phase Imbalance Estimation for Azimuth Multi-Channel ScanSAR System [PDF]
The new concept of combining the azimuth multichannel synthetic aperture radar (SAR) system with the Scan mode was put forward to meet the requirements of future developments in high-resolution and ultrawide-swath SAR design. However, the phase imbalance

Mutual Coupling and Channel Imbalance Calibration of Colocated MIMO Radars
The Multiple-Input Multiple-Output (MIMO) radar combines the signals from multiple transmit and receive elements separately to form a virtual array. Consequently, system imperfections in the MIMO radar caused by channel imbalance and mutual coupling are ...

Channel Imbalance Calibration Based on the Zero Helix of Bragg-like Targets
The calibration of channel imbalances is currently the main concern in polarimetric calibration (POLCAL) since the crosstalk of recent polarimetric synthetic aperture radar (Pol-SAR) systems is lower than −20 dB.

A Computationally Efficient Hybrid Framework for Polarimetric Calibration of Quad‐Pol SAR Data
Polarimetric Synthetic Aperture Radar (PolSAR) calibration is an essential preprocessing step that must be performed to ensure that the data quality is adequate. This, in turn, helps to minimize the propagation of errors in any further data processing or
