Abstract
Continuous Transmission Frequency Modulated (CTFM) ultrasonic sensors can be used to recognise plants. The echo from a plant is modelled as an acoustic density profile. Classification based on features extracted from the echo is more robust than classification based on the echo. Potential applications for this sensing system include landmark navigation and plant sensing for selective spraying of agricultural chemicals.
