Noise Angle Accuracy of Several Monopulse Architectures

Rigorous analysis of four monopulse radar architectures has been conducted to develop the practical angle-tracking accuracy of the systems due to noise. The word ¿practical¿ is used to imply that the systems may have range gates of arbitrary duration and may transmit pulses with arbitrarily shaped envelopes. The accuracy measure used is the mean-squared error (variance) in angle tracking. The four systems considered differ from each other according to the locations of the range gates and ¿matched filters¿ in their architectures.
