In this paper, the principle, performance and measuring result of a high precision pinse-ratio circuit (or analog divider) are described. When the dynamic range of position is 0.05 to 1, and that of energy is 1 to 10V,a position resolution(FWHM) is better than 0.1% of full scale and a integral noniinearity is less than 0.1%.

An investigation is conducted on noise jamming tracking performance of the amplitude-comparison monopulse tracking radar.By the examination of the p.d.f.of the transfer coefficient of the AGC ratio circuit, an approximated time-invariant system model is obtained and the statistical characteristics of the angle error voltage including the upper bound of its variation is then derived.The results show that the jamming signal itself affects only the angle sensitivity and this effect is reduced with the increase of the i.f.amplfier bandwidth and with the decrease of the bandwidth of AGC loop and the narrow filter subsequent to the phase detector, thus providing a useful guide to the estimation of system performance and to the determination of system parameters,
