一、无源定位的发展简况 1.开关管的出现使无源定位被忽视雷达刚出现时,发射站和接收站是互相分立的,当时都采用多站工作方式。它的优点是既能随时关机以无源跟踪方式隐蔽地工作避免攻击,又能有源无源互相转换迷惑敌方。多部站从不同角度观察空情,从各雷达站提取的信息经窄带数据传输,并被集中相关,可抗当时少量的干 First, the passive positioning of the development of a 1. The emergence of the switch so that passive positioning is ignored When the radar has just emerged, the transmitting station and receiving station are separate from each other, were using multi-station work. It has the advantage of being able to shut down at any time to work in a passive way to avoid hidden attacks, but also the conversion of active and passive confuse the enemy. Many stations looked at the air condition from different angles and the information extracted from each radar station was transmitted via narrowband data and was concentratedly correlated to resist a small amount of dryness at that time
