چکیده
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 themwith the Cramér-Rao lower bounds. & 2008 Elsevier B.V.

DOA estimation and multi-user interference in a two-radar system
Multistatic radars utilize multiple transmitter and receiver sites to provide several different monostatic and bistatic channels of observation. Multistatic passive and active radar systems can offer many advantages in terms of coverage and accuracy in the estimation of target signal parameters. Unfortunately, their performances are heavily sensitive to the position of receivers and transmitter...
متن کاملThe Expected Achievable Distortion of Two-User Decentralized Interference Channels
This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...

متن کاملA New Algorithm for the Deinterleaving of Radar Pulses
This paper presents a new algorithm for the deinterleaving of radar signals, based on the direction of arrival (DOA), carrier frequency (RF), and time of arrival (TOA). The algorithm is applied to classic (constant), jitter, staggered, and dwell switch pulse repetition interval (PRI) signals. This algorithm consists of two stages. In the first stage, a Kohonen neural network clusters the receiv...
