Closed formulas for evaluating radar monopulse accuracy

Monopulse is a widely used algorithm to estimate the target angular co-ordinates in radar application. Formulas exist that give approximate values for the accuracy achievable with monopulse. This paper derives simple but accurate closed formulas to estimate the monopulse accuracy by taking into account the radar detection threshold (and then P
_D
and P
_fa
) and the target fluctuation models.
