摘要
In this paper, we investigate the impact of the presence of interfering radar on the target direction of arrival (DOA) estimation performed by the reference radar. The analyzed estimators are the pseudo-monopulse and the maximum likelihood techniques. The importance of the use of codes in multi-user radar system is highlighted in a simple scenario of two radars by calculating the root-mean square error of the estimators in different operational conditions and comparing them with the Cramer-Rao lower bounds.
