WebAn array of active light sensors is mounted on a vehicle for travel above the plants. The array of active light sensors generate an electrical signal from each sensor corresponding to the reflected light from the sensor. A computer system generates a reflectance curve from the array of sensors to determine the location of a plant below the ... WebSep 1, 2024 · - curved wavefront cause reflected echoes to be received at varying times at the different elements - echoes that are received first are held in delay circuitry : until all of the echoes from the same depth have been received - time delays before echo signals from array elements are combined : results in constructive interference of waves WebDirected straight out but since the crystals are arced the pulses travel in different directions as they radiate out.
