Non-contact respiratory measurement in a horse in standing position using millimeter-wave array radar.
Abstract: This study aimed to apply radar technology to a large quadruped animal. We first developed a non-contact respiration measurement system using millimeter-wave array radar for a horse in standing position. Specifically, we measured the respiration of a stationary domestic horse in stables. Simultaneously, we measured the respiration rate using infrared thermography and developed a method for analyzing the radar information while verifying the rate of agreement. Our results suggested that the radar technology detected breathing and accurately measured the respiration of a horse, despite variation in the breathing frequency. To the best of our knowledge, this is the first study to apply a non-contact respiration measurement system using millimeter-wave array radar has been applied to large animals in an upright position, thereby demonstrating its potential application in animal husbandry and welfare.

This research article describes the application of radar technology to measure the respiratory rate of a horse in a non-contact manner and verified the accuracy of its results using infrared thermography.
Objective and Methodology
- The main aim of this research was to develop and apply a non-contact method to measure the respiration of a large quadruped animal like a horse. This was attempted by utilizing millimeter-wave array radar technology.
- The radar was used to measure the respiration of a domestic horse in a standing position inside its stable.
- Additionally, infrared thermography was used to simultaneously measure the horse’s respiration rate as a means for verifying the results given by the radar technology.
Research Results
- The study found that the use of radar technology was successful in detecting and measuring the respiration of a horse. This remained accurate despite variations in the breathing frequency of the horse.
- The researchers also managed to develop a method to analyze the information picked up by the radar during the respiration measurements.
- The agreement rate between the readings from the radar and the infrared thermography offered substantial proof of the veracity and accuracy of the radar-based measurements.
Significance of the Study
- This research is deemed significant as it marks the first instance of a non-contact respiration measurement system using millimeter-wave array radar has been applied to large animals.
- The fact that the animal was in an upright position during the testing adds to the novelty of the study.
- The potential application of this technology in fields like animal husbandry and welfare is particularly noteworthy. It could pave the way for non-intrusive, accurate animal health monitoring systems aiding in better livestock management.
