The probability density function of the monopulse ratio for N looks at a combination of constant and Rayleigh targets
Abstract
The exact probability density function for the 'monopulse ratio' of an amplitudecomparison monopulse radar is presented in closed form. The analysis is valid for multiple looks at any combination of fixed targets, pulsetopulse independently fluctuating targets, and receiver noise. The average receiver noise powers in the difference and sum channels need not be equal. Arbitrary signaltonoise ratio, arbitrary monopulse ratio versus angle characteristic, and arbitrary locations of the targets and jammers in the beam are accommodated. Plots of the density function for various signaltonoise ratios and offaxis location of the targets are included. A linear approximation is introduced, and the exact results are compared to the linear theory when the signaltonoise ratio is 'small'.
