本文介绍了一种用于无人机上雷达图像的 3D SAR 系统。该概念结合了天底指向接收器线性阵列、SAR 技术，并采用线性调频 (LFM) 脉冲波形。该系统具有许多优点：它可以生成感兴趣区域的 3D 图像，避免生成图像上的阴影区域，并且可以获得有利的功率预算。本文描述了我们在信号处理和实验方面的初步工作。使用 Ka 波段雷达的模拟结果和首次地面测量活动说明了该理论。
This paper presents a 3D SAR system for radar imagery onboard an UAV. The concept combines a linear array of nadir pointing receivers, the SAR technique and employs linear frequency-modulated (LFM) pulse waveform. This system has many advantages: it leads to a 3D image of the area of interest, it avoids shadowed zona on the resulting image and an advantageous power budget can be obtained. The paper describes our preliminary works in terms of signal processing and experiments. The theory is illustrated by simulation results and first ground measurement campaigns, using a Ka-band radar.
