摘要：

Range imaging (RIM), which uses multiple frequencies, enables wind profiler radars (WPRs) to measure wind and turbulence with enhanced range resolution. Adaptive clutter suppression, which controls sidelobes by using subarrays, is useful for mitigating clutter contamination. In order to apply RIM and adaptive clutter suppression not only to scientific researches but also to operational monitoring of wind and turbulence, a high-resolution 1.3 GHz WPR, referred to as LQ-13, has been developed. In order to implement the capability of oversampling and adaptive clutter suppression to LQ-13, a digital receiver composed of general-purpose software-defined radio receiver and a workstation is used. By using both RIM and oversampling, LQ-13 is able to measure wind and turbulence with high range resolution. Some measurement results showed that multi-channel signal collection by the digital receiver can be used for adaptive clutter suppression.
