Very High Frequency Omnidirectional Range begins with transmission of frequency modulated signal.

Very High Frequency Omnidirectional Range begins with transmission of frequency modulated signal. Correct Answer False

Very High Frequency Omnidirectional Range begins with transmission of amplitude modulated signal with a constant frequency. The transmitted signal passes through a set of antenna in a circle introducing frequency modulated Doppler onto the received signal. The relative phase angle between amplitude modulated signal and frequency modulated signal is employed to find the location of the source.
