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.
本研究旨在将雷达技术应用于大型四足动物。我们首先开发了一种使用毫米波阵列雷达的非接触式呼吸测量系统，用于站立的马。具体来说，我们测量了厩中静止的家养马的呼吸。同时，我们使用红外热成像测量了呼吸率，并开发了一种分析雷达信息的方法，同时验证了其一致性。我们的结果表明，雷达技术可以检测呼吸并准确测量马的呼吸，尽管呼吸频率有所变化。据我们所知，这是首次将使用毫米波阵列雷达的非接触式呼吸测量系统应用于直立的大型动物，从而证明了其在畜牧业和福利方面的潜在应用。
