The hardware configuration and dynamic array control algorithm as well as parameter design are described coneretely . the results of simulation and operation are given 對(duì)系統(tǒng)硬件配置動(dòng)態(tài)矩陣控制算法及參數(shù)設(shè)計(jì)作了具體說(shuō)明,給出了仿真和實(shí)際運(yùn)行結(jié)果。
Linear array can only provide an azimuth scan ranging from 0 to 180 degree , while circular array from 0 to 360 . by means of recurring moving array excitation , circular array controls the beams ’ orientation simply and neatly , creating a perfect pattern in azimuth and an ideal pattern in pitch 線陣只能有180的掃描范圍,而圓形陣列能夠提供360方位角,通過(guò)循環(huán)移動(dòng)陣列激勵(lì),簡(jiǎn)單而靈活地操縱波束的方位,能夠在方位上產(chǎn)生沒(méi)有方向性方向圖,而在俯仰方向上也有一個(gè)理想的方向特性。
In addition , we analyzed characteristics of every instrument of the test system . as key problems , the control , communication and synchronization , such as relay arrays control and gpib communicatipn , of the virtual instrument system were discussed carefully in the dissertation . we also discussed some anti - jamming solutions of the system 詳細(xì)研究了基于虛擬儀器的測(cè)試系統(tǒng)中對(duì)多種程控設(shè)備的控制方法及系統(tǒng)中的同步方法(負(fù)載電源的模擬電壓控制方法、工業(yè)控制計(jì)算機(jī)與gpib設(shè)備的通信方法;模擬通道采樣的同步方法、測(cè)試程序中數(shù)據(jù)流的同步方法等) 。
