單脈衝雷達的比較器及其訊號產生方法

Abstract

一種單脈衝雷達的比較器及其訊號產生方法。此比較器包括天線陣列、橫向電磁波模態空腔(TEM mode cavity)功率合成器以及切換裝置。天線陣列包括N個天線。橫向電磁波模態空腔功率合成器具有合成埠與M個輸入埠組合，各輸入埠組合具有正相輸入埠與反相輸入埠，N與M為大於1的整數。切換裝置耦接於天線陣列與橫向電磁波模態空腔功率合成器之間，用以將各天線接收的回波訊號傳送至輸入埠組合的其中之一的正相輸入埠或反相輸入埠。其中，橫向電磁波模態空腔功率合成器的合成埠依據輸入埠組合接收的回波訊號產生輸出訊號。 A comparator of a mono-pulse radar and a signal generation method thereof. The comparator includes an antenna array, TEM mode cavity power combiner and a switch device. The antenna array includes N antennas. The TEM mode cavity power combiner includes a combination port and M input port sets, and each of the input port sets has a positive input port and a negative input port, wherein N and M are integer greater than 1. The switch device is coupled between the antenna array and the TEM mode cavity power combiner and used for transmitting the reflected signal received by the antenna array to the positive input port or the negative input port of one of the input port sets. An output signal is generated according to the received reflected signal from the input port sets by the combination port of the TEM mode cavity power combiner.
