Abstract: Receiving polarization processing was primary po rtion of variational polarization radar,was important aspect of radar polarizat ion processing also. This paper focus in discussing realization of amplitude-ph ase weighting and self-adaptive receiving polarization processing arithmetic of receiving polarization processing, along with using high speed acquisition and digital signal processing (DSP) technology, the soft ware and hard ware implemen t of zero intermediate frequency amplitude-phase weighting and optimized polari zation calculate.
