NASA 戈达德太空飞行中心 (GSFC) 高空成像风雨机载剖面仪 (HIWRAP) 是由 NASA 仪器孵化器计划资助的固态双频多普勒雷达。它使用直接数字合成器设备来生成多种波形，包括传统脉冲和线性调频 (LFM) 线性调频脉冲。这封信描述了 GSFC 和遥感解决方案使用的波形，以解决机载脉冲压缩雷达中距离旁瓣和盲距的关键限制。通过在每个发射周期利用由两个脉冲和一个 LFM 线性调频组成的频率分集波形，该系统可提高中高海拔目标的脉冲压缩灵敏度和距离分辨率优势，同时保留雷达和地面附近的传统脉冲数据。介绍了 HIWRAP 在 NASA 中纬度大陆对流云实验期间使用该波形方案获得的数据。
The NASA Goddard Space Flight Center (GSFC) High-altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) is a solid-state dual frequency Doppler radar funded by the NASA Instrument Incubator Program. It uses direct-digital-synthesizer devices to generate versatile waveforms including conventional pulses and linear frequency modulation (LFM) chirps. This letter describes a waveform used by the GSFC and the Remote Sensing Solutions to address the critical limitations of range sidelobes and blind ranges in airborne pulse-compression radar. By utilizing a frequency diversity waveform consisting of two pulses and an LFM chirp at each transmit cycle, this system provides the improved sensitivity and range resolution benefits of pulse compression on targets within the middle and high altitudes while maintaining conventional pulsed data near the radar and the surface. The data obtained by the HIWRAP during the NASA Midlatitude Continental Convective Clouds Experiment using this waveform scheme are presented.
