Resolution Improvement in Preharvest Sensor

Abstract

This work illustrates the benefit of subtracted beam antenna we presented earlier for a sensor system in fruit pre-harvesting. The angular resolution pattern of a receiving antenna that shows how far the unwanted object (fruit) can be eliminated from the desired target (fruit under test) is proposed. The link budget for the beam subtracted antenna is also calculated to indicate the transmitting power for ensuring the receiving power for a normal sensitivity of the sensor. This calculation shows that the beam subtracted antenna can be employed in pre-harvesting of fruits.
