Abstract :
This paper proposes the time space MUSIC technique using the chirp pulse signal of a tracking radar. Direction/time of arrival (D/TOA) estimation characteristics are evaluated for the simulated point sources, simulated extended air targets, and the actual extended air targets. It is shown that the proposed technique is enable to highly resolve and precisely estimate D/TOA of the actual targets covered by one radar beam width.
