Abstract

Ternary correlation filters, which encode modulations of -1, 0 and +1, may be viewed as a logical step beyond binary phase-only filters. Both formulations are motivated by the prospect of relatively simple real-time implementation compared to full complex matched filters. The zero-modulation state of ternary filters affords additional flexibility and control in filter design. In particular both enhanced nontarget discrimination and reduced distortion sensitivity, relative to simple binary phase-only filters, can be achieved simultaneously as demonstrated by correlation simulations reported here.
