    • A nulling direct radiating array (30) that includes a main phased array (32) and a plurality of auxiliary arrays (70, 72, 74) symmetrically disposed about the main array (32). The main array (32) includes a plurality of antenna elements (34) and a beam forming system (56) that generates one or more channels made up of several pixel beams. The pixel beams from the main array (32) are connected to a nulling processor (108) along with the combined signal from the antenna elements (80) of the auxiliary arrays (70, 72, 74). An adaptive weighting network (112) and an adaptive weight generator (114) within the nulling processor (108) determine whether a jamming signal exists in the channel beam, and weight the pixel beams from the main array (32) accordingly to block the jamming signal. The auxiliary arrays (70, 72, 74) provide a wider beam aperture that is able to more narrowly define the null in the radiation pattern of the main array (32).
    • 一种归零直接辐射阵列(30),其包括主相位阵列(32)和围绕主阵列(32)对称设置的多个辅助阵列(70,72,74)。 主阵列(32)包括多个天线元件(34)和产生由多个像素束构成的一个或多个通道的波束形成系统(56)。 来自主阵列(32)的像素束与来自辅助阵列(70,72,74)的天线元件(80)的组合信号一起连接到归零处理器(108)。 归零处理器(108)内的自适应加权网络(112)和自适应权重发生器(114)确定信道波束中是否存在干扰信号,并相应地对来自主阵列(32)的像素波束进行加权以阻止干扰 信号。 辅助阵列(70,72,74)提供更宽的光束孔径,其能够更窄地限定主阵列(32)的辐射图案中的零点。

    • A sidelobe canceler includes a main antenna, an array of sub-antennas, a subtractor having a first input connected to the main antenna, a main-array processor and M sub-array processors. The main-array processor multiplies the outputs of the sub-antennas with weight coefficients using correlations between the sub-antenna outputs and the subtractor output and combines the multiplied signals into a signal, which is coupled to the second input of the subtractor. The signal-to-noise ratio of the subtractor output is maximized by an adaptive matched filter. Each sub-array processor multiplies the sub-antenna outputs with weight coefficients using correlations between the sub-antenna outputs and a decision signal. The multiplied signals are summed to produce an output of each sub-array processor, which is combined with the outputs of the other sub-array processors into a first diversity-combined signal, the latter being combined with the matched filter output to produce a second diversity-combined signal. Intersymbol interference is removed by an adaptive equalizer from the second diversity-combined signal according to a decision error so that the decision signal is produced and applied to the sub-array processors. Different amounts of delay are introduced to the outputs of (M - 1) of the sub-array processors so that the output of the i-th sub-array processor is delayed by (i - 1) T , where i = 2, 3, ....., M, and different amounts of delay are introduced to the decision signals applied to (M - 1) of the sub-array processors so that the decision signal applied to the j-th sub-array processor is delayed by (M - j) T , where j = 1, 2, ....., M-1. The total amounts of delay associated with each of the M sub-array processors is equal to (M-1)τ.
