Abstract :
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 noise and cross interference terms. Emulation results verify the validities of the techniques.
