摘要

在本文中,我们提出了一种调频波形的设计,当用于雷达脉冲压缩系统时,可以产生超低范围的旁瓣电平,而无需在发射机侧进行幅度递减。结果表明,该设计满足星载降水雷达工作对波形设计的具体要求。从相位和幅度的慢变误差和快变误差两方面对误差性能进行了评价。我们用一个实际系统的修正数据来说明误差的影响。

Improved waveforms for satellite-borne precipitation radar
In this paper we present a design for an FM waveform which, when used in radar pulse compression systems, results in ultra-low range sidelobe levels without the need for amplitude tapering at transmitter side. We show that the design meets the specific requirements upon wave-form design that arise from the operation of a satellite-borne precipitation radar. The error performance is evaluated in terms of both slow and fast varying errors on phase and amplitude. We illustrate the effect of errors with modified data from a real system.
