Multipath Suppression of Radio Navigation Transmitter Signal Based on Linear Sweep Carrier

Multipath Suppression of Radio Navigation Transmitter Signal Based on Linear Sweep Carrier

Multipath interference is the main error source for radio navigation system high-precision positioning in complex environments. Multipath suppression and elimination are critical for radio navigation systems. A linear sweep carrier signal system is proposed to improve the multipath mitigation perfor...
