Abstract : A technique to reduce radar pointing errors due to glint using frequency agility and linear amplitude weighting is presented. Frequency agility is used to obtain independent samples of target position. The samples are then processed using a linear weighting scheme which determines target position by the amplitude of the return signal. The simple method of choosing the target position corresponding to the echo-signal with the largest amplitude is the most effective. This weighting method when applied to independent target returns reduces the RMS tracking error substantially. The resulting reduction in RMS tracking error is developed into an equation dependent upon the original glint tracking error, and the number of returns weighted. (Author)
