Joint Estimation of Time-Frequency Signature and DOA Based on STFD for Multicomponent Chirp Signals

Table 1

Simulation parameter setting.

	Initial frequency	Chirp rate	DOA	SNR
Signal 1	= 2 MHz	= −1.875 MHz/s	−35°	0 dB
Signal 2	= 1 MHz	= 1.25 MHz/s	50°	0 dB
Signal 3	= 0.5 MHz	= 1.25 MHz/s	20°	0 dB
