Wideband chirp parameter estimation in sensor arrays through DPT
S. Lie, A.R. Leyman, Yong Huat Chew · Electronics Letters · 2003
An estimation technique for multiple constant amplitude chirp signals is proposed. The estimation of the initial frequencies, frequency rates and direction of arrivals of individual chirp signals is achieved with 1D searches, hence it is computationally attractive. Simulation and comparative results are given to show the effectiveness of the technique.
