Effect of Phasing Sector Angular Extent in FM Reticles

Abstract

Spinning FM reticles often determine target location by using a combination of a phasing sector to establish angular target location and a radial frequency variation to establish radial target location. Typically, the phasing sector of this type of reticle consists of a semicircular transmissive sector with the other semicircular sector providing FM modulation. This paper presents a technique for increasing the useful power of the FM modulation signal. This is accomplished by matching the phasing sector geometry to the size that corresponds to the period of the modulation frequency. This type of reticle is compared and contrasted with the more typical semicircular phasing sector reticle in both the time and frequency domain.
