Performance of the improved channel equalization method for Wideband Digital Array Radar
Yong Ran, Xuegang Wang, Lin Zou · 2009
Channel equalization algorithm must be used to achieve the idea effect of digital beamforming in Wideband Digital Array Radar. Performance of based on Inverse Fourier Transform method deteriorate in low signal to noise ratio (SNR) environment. An improved method is presented. This method only calibrate the error of signal in passband not the differences caused by noise outside the band. Finally, simulations are carried out with 20dB SNR and comparisons are made to demonstrate the performance improvement of improved calibration method.
