Frequency-Domain Equalization of Channel Inconsistency for Wideband Navigation Anti-jamming Receiver Based on Uniform Circular Array

The channel inconsistency will generally degrade the performance of a multichannel system. So it's necessary to equalize the mismatch of each channel. In the navigation anti-jamming receiver based on array antennas, the channel inconsistency will lead to a distortion of the beam and degrade the anti-jamming capability. This paper proposes a frequency-domain equalization method to compensate the channel inconsistency and improve the anti-jamming capability of the receiver. The simulations show that the method is highly effective and can improve the system performance.
