摘要

提出了一种小型、低成本、p波段机载偏振合成孔径雷达(SAR)的初步设计研究。该设计应瓦赫宁根大学和婆罗洲猩猩生存基金会(BOS)的要求,在印度尼西亚进行森林生物量监测。建立了应用需求,并推导了主要雷达参数。本文还介绍了基于商用现成组件的系统初步设计。该系统的一些新颖之处是使用直接数字合成(DDS)来进行调制,使用双极化微带方形贴片天线,以及减小了系统的尺寸和功耗。

P-SAR: an advanced miniature synthetic aperture radar for forestry applications. Preliminary design
A preliminary study of the design of a small, low cost, P-band airborne, polarimetric synthetic aperture radar (SAR) is presented. The design was requested by the Wageningen University and the Borneo Orangutan Survival Foundation (BOS) to carry out forest biomass monitoring in Indonesia. The requirements of the application are established and the main radar parameters are derived from them. A preliminary design of the system, based on commercial off-the-shelf components is also presented. Some novelties of the system are the use of direct digital synthesis (DDS) to perform the modulation, the use of dual-polarized microstrip square patch antennas and the reduced size and power consumption of the system.
