一、概述 AN/DPN—41(XE—1)应答机是一种S波段的弹载雷达应答机。其第一批产品是在1955年6月到1958年6月期间生产的。它的功能类似于AN/DPN-19。接收机是一种直接检波视频放大式的,它采用了一种三腔予选器以保证获得高的选择性,发射机使用了一种安装在发射机振荡器腔体内的笔形三极管。应答机不仅完成雷达跟踪作用,而且还完成遥控的作用。应答机由射频、视频、编码—调制器和发射机四部分组成。视频部分完成信号的选择和检测,并在发射机工作期间保护检波器。为了满足这些要求,研制了一种可调的三腔予选器,予选器
I. Overview The AN / DPN-41 (XE-1) transponder is an S-band airborne radar transponder. The first of its products was produced between June 1955 and June 1958. Its function is similar to AN / DPN-19. The receiver is a direct-view video amplifier that uses a three-cavity preselector to ensure high selectivity. The transmitter uses a pen-shaped transistor mounted in the transmitter’s oscillator cavity. The answering machine not only completes the radar tracking but also completes the remote control. Answering machine by radio frequency, video, code - modulator and transmitter four parts. The video part completes signal selection and detection and protects the detector while the transmitter is operating. In order to meet these requirements, an adjustable three-chamber preselector and preselector have been developed
