Abstract In order to deepen the application of microwave technology in the field of precise target spraying,the performance of the microwave detector, the detecting effect and the influencing factors were studied and analyzed. By using frequency modulated carrier wave microwave sensors, detecting experiments in different environmental conditions were performed on simulated targets and real plants of different entities respectively. The experimental results show that light intensity, temperature and humidity have little influence on the detecting effect while the size of targets has great impact on the detecting effect. In the experiments, the varieties of the plant had small impact on the detection, while the shapes of the plant(e.g. density and size) and the distance between the plants were key factors to the detection. In the application of plant targeting, the microwave detection is more suitable to the huge object with luxuriant leaves. The larger the reflection area of the object is, the better the detection performance is and the farther the detection distance is, the better the detection effect is. The distance between the plants is related to the resolution monotone of the detector.
