Optimization of Sub-band Pulse System Based on Modulated Filter Banks
Wideband radar with high range resolution can provide a wealth of objective information,but large volumes of data and calculations as a constraint to the problem of Wideband radar signal processing. Sub-band signal processing can decompose high-speed broadband signal to a low-rate narrow band signals,greatly reducing the complexity of radar signal processing. The modulated filter design is the key of sub-band signal processing. Base on the research of modulated filter banks,M-band modulation filter applied to the sub-band pulse compression,a new optimization algorithm - Lagrange multipliers was presented. This method has higher efficiency,it is able to design filter banks of different lengths and same length.
