Raytheon was awarded a $102.54M fixed-price-incentive domestic and foreign military sales contract for the phased array tracking radar to intercept of target digital sidelobe canceller and peripheral electronics assembly box modification kits and initial spares production.
Mitsubishi Electric developed the antenna with Hiroshima Institute of Technology, and received support from the Japan Science and Technology Agency's A-STEP program under a project entitled "Development of a novel resin ridge waveguide antenna with eminent low sidelobe."
Mitsubishi Electric developed the antenna with Hiroshima Institute of Technology, and received support from the Japan Science and Technology Agency's A-STEP program under a project entitled "Development of a novel resin ridge waveguide antenna with eminent low sidelobe." For the project, a large-scale array antenna prototype consisting of about 2,000 elements was manufactured and evaluated.
New spatial measurement requirements include sidelobe levels, dynamic beam characteristics, and spatial variations of EVM and ACPR.
Many waveform design studies have focused on the low autocorrelation sidelobe [6-10], which can improve the detection performance for weak targets.
Figures 6 and 7 show that when the snapshots are big (K > 20), the amplitudes of mainlobe in the algorithm with literature [6] and the algorithm with this paper are equal; the amplitude of sidelobe in the algorithm with this paper is below -15 dB, which is slightly superior to the algorithm with literature [6]; the above two methods are both superior to MVDR algorithm.
The signal in (3) is SU signal in frequency domain, whose sidelobe power in frequency bands of the adjacent LUs decays with 1/[f.sup.2][N.sub.s] as shown in Figure 1, resulting in high OOBR.
In this technique all the subcarriers are multiplied by complex weights so to minimize the sidelobe power.
3) The radar images obtained by conventional SAR imaging algorithm have a severe sidelobe which is a considerable problem to overcome.
The whole angle space can be subdivided into mainlobe region [[OMEGA].sup.ML] and sidelobe region [[OMEGA].sup.SL].
Obviously, the synchronization sequence should have a low sidelobe level (SLL) of correlation function that being defined as
Los niveles de de lobulo lateral o sidelobe level (SLL) se mejoraron a traves de la tecnica propuesta en (Gruszczynski, Wincza y Sachse, 2006), incrementando la cantidad de elementos radiantes del arreglo.
