A two-pole filter was proposed as a detector for a scanning radar. The optimum values of the filter coefficients were found and are approximated by a simple expression. The optimum two-pole filter requires a 0.15-dB increase in signal-to-noise ratio in order to provide the same detection capability as the optimum detector and yields azimuth estimates whose standard deviation is within 15 of the Cramer-Rao lower bound. The estimator is simple to implement since it avoids the storage requirements of the moving window detector and the bias complications of the feedback integrator. Author
