360GHz辐射计探测地面目标试验

Experiments on detecting ground targets with 360 GHz radiometer

为验证亚毫米波辐射计在弹药末制导中的应用可行性,计算了不同天气条件下天空亮温和视在温度,利用360GHz辐射计对地面金属目标和涂层隐身目标进行了模拟探测试验。计算和试验表明,在寒冷干燥的季节,辐射计可以探测到地面金属目标,随着温度和湿度的升高,辐射计很难再探测到目标;对于高温涂层隐身目标,辐射计可以探测到,而不受天气的限制。

In order to verify the feasibility of submillimeter wave radiometer in the terminal guidance, the sky brightness temperature and apparent temperature are calculated. Moreover, the experiments for detecting ground metal and coating stealth targets are carried out. The calculations and experiments show that the radiometer can detect ground metal targets in the cold weather and can not detect it with increasing temperature and humidity. Nevertheless, the radiometer can detect high-temperature coating stealth targets regardless of the weather.
