有源相控阵雷达系统技术参数测试

Technical Parameter Test of an Active Phased Array Radar System

有源相控阵雷达采用分布式的发射机和接收机,雷达发射系统的辐射功率和接收系统的灵敏度等指标无法直接测量。通过测量有源相控阵雷达中雷达辐射功率与发射天线增益积和接收天线增益与系统噪声温度比来反映雷达系统指标是合理的,并给出了相应的测量方法。

Since the distributed transmitter and receiver are adopted in the active phased array radar, the specifications such as test radiation power of the transmitter, sensitivity of the receiver, etc cannot be tested directly. It is reasonable to test the product of radiation power and the transmitted antenna gain and the ratio of the received antenna gain to noise temperature in the active phased array radar, because they can reflect the radar system specifications, and the corresponding test method is given.
