Abstract

Under a Phase II SBIR from NASA, a data collection radar was developed to support the NASA program in Automated Napof the Earth (ANOE) guidance for helicopters. The developed radar is comprised of two parts, a sensor front end and a digital signal processor. The sensor front end is a wideband, linear FM, 94 GHz millimeter wave radar with dual circular polarization and dual axis monopulse. It provides 10 dB signal-to-noise on a 5 m/sup 2/ target at 1 km. Digital signal processing is employed to provide range compression and monopulse angle beam sharpening. To remain within funding limitations the radar generates a reduced size raster scan of 12.5/spl deg/ /spl times/250/spl times/320 m for collecting data. The range resolution is 3 m, the angle bin size is 0.34/spl deg/, and there is frequency agility over 600 MHz. Data was collected from a ground location to verify operation of the radar. The data is displayed in a C-scope format using NASA supplied "Grid World" software.

地球自动探测(ANOE)数据收集雷达

根据NASA的第二阶段SBIR，一种数据收集雷达被开发出来，以支持NASA的直升机自动地球探测(ANOE)制导项目。研制的雷达由传感器前端和数字信号处理器两部分组成。传感器前端采用双圆偏振双轴单脉冲的宽带线性调频94ghz毫米波雷达。它在1公里处对5m /sup / target提供10db信噪比。采用数字信号处理提供距离压缩和单脉冲角波束锐化。为了保持在资金限制内，雷达产生12.5/spl度/ /spl次/250/spl次/320米的缩小尺寸光栅扫描以收集数据。距离分辨率为3米，角仓尺寸为0.34/spl度/，频率捷变超过600 MHz。从地面位置收集数据以验证雷达的操作。数据使用NASA提供的“网格世界”软件以C-scope格式显示。
