Abstract

Direction of arrival (DOA) is an important parameter to be measured in pulse compression radar (PCR) systems. It is more favorable for DOA estimation to be done after pulse compression, because the targets have been separated in range domain and usually have higher SNR. But after pulse compression, only a single snapshot is available in each range cell. As a result, conventional DOA estimation methods can't be done frequently since they need many snapshots to work. To solve this problem, a single-snapshot DOA (SSDOA) estimation method based on compressed sensing is proposed in this paper. In spite of single-snapshot estimation, the proposed method provides higher estimation accuracy and target resolution without knowing the number of targets, especially in the case of multiple targets in the same range cell.
