Abstract
This paper presents a method to identify the maturity of durian using radar equation. The measurement system consists of two identical square patch antennas acting as a transmitter and a receiver. The return loss of the transmitter and the transmission coefficient at the receiver are measured using network analyzer. These measured data are used to determine the ratio of the effective reflection coefficients for two different frequencies at the interface between air and durian. In this step, the radar equation is applied. In this experiment, ten mature and ten immature durians are chosen by an experienced farmer. The measured data of fourteen durians are used for training the system using the support vector classification. The measured data of another six durians are used for testing the system. The results show that the performance of the system is acceptable.
