| 摘 要： | 通过星载应用时的基本特点分析,提出了四元十字形阵相位干涉仪测向方法。从单站无源定位原理出发,分析了3个干涉仪相对一个基准干涉仪的到达角信号时差,并得到3个信号相位差,但因在实际使用中干涉仪相位差测量值会出现模糊。最终提出一种信号模拟器上位机设计,与DSP通过USB接口进行交互,传输空中平台掠过一个目标所产生的所有脉冲数据。

| Abstract: | By analyzing the basic characteristics of spaceborne applications, a finding method with phase interferometer of four antenna cruciform array is proposed. From a single station passive location departure, the time difference of arrival angle signals between three interferometers relative to a reference interferometer are analyzed with three signal phases obtained. But the actual value of the phase difference measurement interferometer is blurred. A signal simulator software design is proposed, which interacts with DSP via the USB, and transmits the data of all pulses when the aerial platform passes a target. |
