Source parameter estimation is an appealing research topic over decades in the field of array signal processing. The estimation performance of multidimensional parameter directly influences the effect of subsequent procedures, such as signal detection and filtering. In this paper we give a brief review of direction of arrival (DOA) and polarization parameter estimation methods. Based on a sensor array...
In this paper, we modify the classic manifold separation technique (MST), aiming to reduce its dependence on high signal-to-noise ratio (SNR) measuring environment. According to the analysis of the array response, it is demonstrated that to maintain a correct phase relationship between the received data at different calibration angles is indispensable for the application of MST. Thus, we slightly...
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...
