Description
Summary:Target detection and localization is an active research area due to its importance in a wide range of application such as biomedical and military applications. In this paper, a novel method for the detection and estimation of signal parameters such as range and direction of arrival for multiple far- field target using wideband echo chirp signals is proposed. Sonar and radar are the active detection systems transmit well defined signals into a region of interest. A model preprocessing procedure is designed for the echo signal. The parameters estimation method for multiple targets is developed based on the Linear Canonical transform and the Fast Root MUSIC algorithm which is a high resolution DOA estimation method originally proposed for any arbitrary arrays to reduce the computational complexity in existing systems. The proposed method provides high accuracy of detection and resolution even in very low SNR values.
