文摘Traditional monopulse radar cannot resolve two targets present in one range and Doppler cell by means of the monopulse ratio. A novel algorithm is proposed to estimate the directions of two steady targets with two pulses.

Furthermore, the pulse pair selection criterion and the estimation method with multiple pulses are given.
