In this paper a cross-correlation method and a cross-correlation-LS method are presented to estimate wideband chirp signal DOA. After calculating the conjugate product of the referenced sensor and the other sensors, the TLS-ESPRIT approach is applied. Then, estimation results of multiple sensors are synthesized by least squares to decrease errors. Methods here are simple and effective. They can suppress...
Spatial polarimetric WVD matrix is constructed using Wigner-Ville distribution (WVD), a new algorithm is proposed for two-dimension (2-D) direction of arrival (DOA) and polarization of linear frequency modulation (LFM) signals based on a single electromagnetic vector sensor. The signals with different time-frequency (t-f) signatures permit the source discriminations through the flexibility of selecting...
Based on uni-vector-sensor, a new algorithm was proposed for two-dimension (2-D) direction of arrival (DOA) and polarization of the wideband cyclostationary sources embedded in colored noise. By sufficiently utilizing the cyclostationarity of the signals, the proposed method not only performed signal selective DOA, but also suppressed additive colored noise and wideband interference. The signal detection...
