压缩采样步进频率雷达(SFR-CS)

Step-Frequency Radar with Compressive Sampling (SFR-CS)

Sagar Shah, Yao Yu, Athina Petropulu

摘要:

步进频率雷达(SFR)是一种高分辨率雷达方法,其中多个脉冲以不同频率发射,覆盖宽频谱。所获得的分辨率直接取决于所使用的总带宽,或者等效地,取决于发射脉冲的数量。本文提出了一种新的SFR系统,即SFR与压缩采样(SFRCS),实现了相同的分辨率作为一个传统的SFR,而使用显着减少的带宽,或等效的,发送显着更少的脉冲。这种带宽的减少是通过采用压缩采样的思想和利用目标在距离速度空间的稀疏性来实现的。

英文摘要:

Step-frequency radar (SFR) is a high resolution radar approach, where multiple pulses are transmitted at different frequencies, covering a wide spectrum. The obtained resolution directly depends on the total bandwidth used, or equivalently, the number of transmitted pulses. This paper proposes a novel SFR system, namely SFR with compressive sampling (SFRCS), that achieves the same resolution as a conventional SFR, while using significantly reduced bandwidth, or equivalently, transmitting significantly fewer pulses. This bandwidth reduction is accomplished by employing compressive sampling ideas and exploiting the sparseness of targets in the range velocity space.
