摘要/Abstract

摘要：

针对使用垂直发射阵指向性设计的方式进行影区探测时，传统束控方法波束主瓣随阵元数增加变窄，无法覆盖整个影区的问题，本文提出一种分集束控的信号发射策略，该策略下发射信号波形被设计为多个长度相等的子脉冲，并通过相位控制令不同子脉冲对准不同角度形成波束以照亮整个影区。文章给出了使发射增益最大化的参数选取方法，并提出通过多模板联合匹配滤波的方式，合理选择副本信号以达到将各子脉冲的能量叠加以达到进一步获取增益的目的。仿真结果表明，相比较于传统束控方法，所提出的发射策略能够达到照亮整个影区并取得高发射增益的效果，具有明显优势。

Abstract:

In response to the problem that while using the vertical transmission array directional design for shadow zone detection, the main lobe of the beam in traditional shading technique narrows with the increase of the array elements number and cannot cover the whole shadow zone, this paper proposes a signal transmission strategy of diversity shading. Under this strategy, the transmitted signal waveform is designed as multiple sub pulses of equal length, and different sub pulses are aligned at different angles through phase control to form a beam that illuminates the entire shadow zone. The article provides the parameter selection method for maximizing the transmission gain and proposes the use of multi template joint matching filtering to reasonably select replica signals to achieve the goal of superimposing the energy of each sub pulse and further obtaining gain. The simulation results show that compared to traditional shading method, the proposed emission strategy can simultaneously illuminate the entire shadow zone and achieve high transmission gain with significant advantages.

Key words: shadow zone target detection, vertical transmit array, transmission gain, subpulse, shading
