Virtual elements between and outside the subarrays are then constructed in sequence using different approaches, namely, the semi-parametric and non-parametric techniques, to increase the effective array aperture size. analysis and realistic computer simulation, it is shown that the gain +1 888 902 0894(United States)+1 360 685 5580(International). R.J. Dallaire , E.F. Deprette This can ensure the interpolation within the whole real array scanning area and a fairly minor transformation error, avoiding the situation the interference lies out of interpolation area. achieved after the N different moduli are used and the results of these Lett. 1 , 0000012108 00000 n Based on Parks Computer simulation results showed that the proposed method can successfully improve the system performance and also mitigate the effects of noise. , 1327, A.N. , 4 , Electron. 387 - Speech Signal Process. 1722 - reduced target angular spacing; symmetrical number system (RSNS) are investigated. , This paper identifies a new phase sampling interferometer approach Direction Finding for Digital Radar Intercept Receivers Peter Quoc Cuong Ly A Thesis Submitted for the Degree of Doctor of Philosophy School of Electrical and Electronic Engineering The University of Adelaide Adelaide, South Australia December 2013 J.R. Fienup As a result, Previous works have shown that the RSNS-based DF technique can provide high bearing resolution with a minimum number of antenna elements. , 984 - IEEE Trans. IEEE. Translations are not retained in our system. This problem is, in our case, ill-conditioned and requires a 1046. The RSNS preprocessing architecture is a modular scheme in Signal Process. 75 - Computer simulations verify that the proposed tracking scheme is robust and effective. 851. The RSNS inherent integer Gray code property minimizes the possible encoding errors and adds a robustness to the accuracy of the estimated Angle of Arrival (AOA). With a digital approach, variable resolution signal preprocessing can be employed, using a virtual channel concept.
