Coherent adaptive detection in MIMO radars
Coherent adaptive detection in MIMO radars Abbas Sheikhi1 and Ali Zamani2 Abstract -- The superiority of Multiple-Input Multiple-Output (MIMO) radars over the conventional phased array radars has been recently shown in many aspects. The MIMO radars have better detection performance and can extract target information more precisely than phased array radars. In this paper, for the first time, the pr
CFAR target detection based on Gumbel distribution for HF radar
CFAR target detection based on Gumbel distribution for HF radar Anna L. Dzvonkovskaya' and Hermann Rohling2 Abstract -- High frequency (HF) radars are capable to detect and track targets at extremely long ranges. But the signal environment that includes external noise, different kinds of clutter and interference will significantly limit the detection and system capability. This paper considers a n
Bayesian regularization in the theory of STAP
Bayesian regularization in the theory of STAP Valeriy Mikhaylovich Orlenko' and Yakov D. Shirman2 Abstract -- After adding some details to Melvin's overview on theory and technique of STAP, we point out the role of accounting for Bayesian methods in adaptation theory. In this regard, we develop the relationship between STAP and CFAR shown by E. Kelly but from Bayesian positions. Index Terms -- Spa
Analysis of radar system performance and interference in an air traffic control environment
Analysis of radar system performance and interference in an air traffic control environment Roland Mallwitz' and Albert Walberer2 Abstract -- In the Air Traffic Control (ATC) environment several systems are using the same frequencies. Technical or operational changes in one system have impact on self-interference within the same system as well as on the operation of the other systems. This paper g
A case study on the design of a clutter plotmap-based plot classification mechanism
A case study on the design of a clutter plotmap-based plot classification mechanism Piet van Genderen Abstract -- Many fielded state-of-the-art radars suffer from excessive false alarm rates, at least at times. Various mechanisms have been devised in order to improve the signal-to-clutter ratio in general, but control of false alarms remains to be an issue for the designers. This paper discusses t
