Application of Doppler Radar for Wildlife Detection in Vegetation

Abstract The objective of this paper was to test the suitability of Doppler microwave radar for the detection of wild animals hidden in grassland in front of the harvester. The ability of Doppler radar HB100 sensor to detect a dog or a human person hidden behind different types of crops was tested in laboratory conditions. Relative movement between the radar and the observed object was secured by the assembly acting as mathematical pendulum. The radar always moved in front of different crop samples (arranged in two or one line). The dog or human person was situated behind the crop. In five out of seven cases, the sensor was able to detect the human person. Only in two out of seven cases, the sensor was able to detect the dog. Nevertheless, it can be concluded that microwave radar sensor can be a useful device for detection of wild animals in the crop. Next research is needed in order to better explain the influence of disturbing factors on the measurements.
