文摘 在星载雷达高度计中,误差分析是其核心内容之一.而其中幅度和相位误差一直是设备误差中相当重要的一项.利用成对回波理论推导了幅度和相位误差带来的距离旁瓣,并将旁瓣与测高误差对应起来,结合具体参数进行了定量分析,对系统的幅度及相位误差进行了估算.
其他语种文摘 Radar altimeter has become one of the most useful microwave sensing instruments for observing the earth in the past three decades, and the results from several successful missions, such as Geosat^ERS] + 2 and Topex,has been widely used in many geodesy field, particularly in ocean topography. Erroi analysis is one of the core techniques in the design of Spaceborne Radar Altimeter, because the altimetei data may be impractical for some application cases without adequate precision. Amplitude and phase ripples of the RF system are important error sources in height measurement. This paper deals with theerror issue with the help of the well-established tool "paired-echo theory". Firstly, we consider tlianthe ripples have the sinusoid forms, and then we can convert these ripples into range side lobes. On tht other hand, we establish the form of the side lobe and derive the relationship between side lobes and heigh-bias. In this way we can establish the relationship between amplitude (phase) ripples and height bias. Anc finally, applying this method to a practical system, we can get some quantitative requirements for the amplitude and phase ripples. These requirements are very critical in radar altimeter design.
