ANGLE TRACKING ACCURACY OF PHASED ARRAY RADARS

Abstract

The angular accuracy of phase array radars, with assumptions appropriate to the problem of hardpoint ballistic missile defense, is discussed. An equation is derived relating angular accuracy to the signal-to-noise ratio in individual channels of the array and to random component errors in the individual channels. This equation is applicable to arrays with non-uniformly spaced elements, which are often considered for use in hard point defense systems. Smoothing of radar data to obtain estimates of angle and angular rate for interceptor guidance is also discussed.
