运用亮点分布图识别目标的要害部位在实际应用中是很有价值的,它的实现主要是通过数字内插多波束形成技术来完成的。这种技术同传统的波束形成方法相比具有精度高、运算量小、编程简单的特点,并且可以有效地解决对于硬件采样率过高而给存储硬盘速度及容量上带来的问题,降低了对A/D、数据存储量及传输带宽的要求。本文详细讨论了数字内插多波束形成的原理并给出了计算仿真的结果
The use of bright spot distribution to identify the key areas of the target in practical applications is very valuable, and its implementation is mainly achieved by digital interpolation multi-beamforming technology to complete. Compared with the traditional beamforming method, this technique has the advantages of high precision, small amount of operation and simple programming, and can effectively solve the problems caused by excessively high hardware sampling rate and storage capacity of the storage hard disk, A / D, data storage and transmission bandwidth requirements. This paper discusses in detail the principle of digital interpolating multi-beamforming and gives the result of computational simulation
