Abstract

Antenna cross-polarization isolation is one of the important specifications of radar systems using the phase-comparison angular measurement algorithm. In this paper, the effect of antenna cross-polarization isolation on the angular measurement error of this phase-comparison algorithm is modeled and analyzed. First, a mathematical model of the phase-comparison angle measurement algorithm with antenna cross-polarization components is developed. Subsequently, the detailed effects of antenna cross-polarization isolation on the angular measurement accuracy are given in the context of system engineering experience, and then quantitative conclusions are given. The proposed analytical model and quantitative results can be used in the measurement accuracy analysis of the phase-comparison monopulse angle measurement algorithm for radar systems. And these results can be also used as a criterion in specifying the antenna cross-polarization isolation in a radar system design.
