The use of multiple antennas on a synthetic aperture radar (SAR), i.e., multichannel SAR, offers benefits such as improved ambiguity suppression for moving target indication (MTI) and imaging large swaths (Goodman, N.A. et al. 2002; Ender, J.H.G., 2000), improved signal-to-noise ratio (SNR) (Younis, M. et al., 2003) and the potential to suppress spatial(More)
Knowledge of radar sea-clutter phenomenology allows accurate models to be developed for assessing target detection performance. The majority of work in this area has been at low-grazing angles from clifftops or wave tanks and does not consider scattering in the high grazing angle region beyond 10 •. To improve our understanding at high grazing angles 15 •(More)
Rare-event Monte Carlo (MC) simulation is useful for estimating the threshold level for radar systems where conventional methods do not work and crude MC is not feasible. In this paper, a conditional Monte-Carlo technique, well-adapted to subexponential clutter distributions, is successfully applied to high-resolution airborne maritime radar systems that(More)

We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at √ s NN = 200 GeV. The evolution of the spectra for transverse momenta p T from 0.25 to 5 GeV/c is studied as a function of collision centrality over a range from 65 to 344 participating nucleons. We find a significant change of the spectral shape between p¯ p and(More)
In discrete-event simulation (DES) involving radar systems, one is concerned with tracking the evolution of detection probability as explicitly simulated successive scans elapse. The survival-function based FFT technique discussed here constitutes an improvement over a previously developed approach, that provides speed and efficiency in maintaining and(More)
