Mitigating the multipath effects of low angle monopulse tracking by even difference pattern

In this study, low angle monopulse DF error due to multipath is dealt with using even difference pattern in a monopulse system. It is shown that the complex angle processing based on this approach has a potential to solve the problem. The multipath problem is modelled using both the specular and the diffuse scattering, while the random nature of the latter is also taken into account.
