摘要: 微电子技术的快速发展使得固态有源相控阵天线在雷达中的应用日益普及,对于采用固态有源相控阵天线的雷达,如果为了降低旁瓣而进行加权,在使用雷达方程进行性能评估时必须考虑加权损失。针对这一问题进行了理论推导,并给出了加权损失的计算公式。

Abstract: With the rapid development of microelectronics,the application of solid-state active phased array antenna in radar becomes more and more popular.For the radar with solid-state active phased array antenna,the weighting loss must be considered while using radar equation for performance evaluation if weighting is used to reduce side lobe.The theoretical derivation of this problem is carried out and the formula to calculate the weighting loss is derivated.

Key words: radar, phased array antenna, solid state active phased array antenna, radar equation
