Abstract
The operation of a millimeter-wave interferometric radar for estimating the angle of a target is discussed in this paper. The transmitter emits a linear frequency modulated (LFM) signal, ranging from 37 GHz to 39 GHz. The millimeter-wave interferometric receiver is composed by two receive antenna elements separated by 51 cm (64.6λ). The number of sidelobes in the radiation pattern will change as a function of frequency, generating a frequency response that can be transformed to the angle of a target. The theory behind the technique is explained, supported by the experimental measurements.
本文讨论了毫米波干涉雷达在目标角度估计中的工作原理。发射机发射线性调频(LFM)信号，范围从37 GHz到39 GHz。毫米波干涉接收机由两个相距51 cm (64.6λ)的接收天线单元组成。辐射图中的副瓣数将随频率的变化而变化，产生频率响应，该频率响应可以转换为目标的角度。该技术背后的理论被解释，由实验测量支持。
