Frequency Broadband Signal MVDR Adaptive Beamforming Method and Application
In this paper, frequency broadband signal beamforming methods of digital array radar (DAR) are researched and broadband signal adaptive beamforming is realized through MVDR rule. Simulation and comparison sbow that blocked DFT beamforming method has advantage of little calculating quantity. For non-superposition of each block destroy the relativity of signal, blocked DFT make aberrance to pulse compression and take bad influence in succedent processing. Sliding-window DFT beamforming can achieve good performance of pulse compression, but it has large calculating quantity. Improved DFT beamforrning method has the same calculating quantity with blocked DFT method, and it doesnt destroy the relativity of signal so that it can achieve good performance of pulse compression and in succedent processing. Im proved DFT beam forming m ethod is fit for used in engineering. The result of its application in DAR has been given.
