Abstract :
A multi-channel structure using half-band filter is presented as poly-phase filter to divide the wide frequency band of the Doppler radar echo into 1-1 pairs. In most of the traditional system, this filter adopts FIR (Finite Impulses Respond) structure to get linear phase and simplify the design ignoring resource consumption. Here a four-channel half-band filter based on poly-phase IIR (Infinite Impulse Respond) structure is carried out. This IIR structure can also get linear phase but need less resources. This design is simulated using Simulink in MATLAB followed by prototype C code generation and performing on the target hardware platform. The results show the correctness of this method.
