Five seconds later the last radar target showed the aircraft tracking 217 degrees magnetic at 131 knots and with a transponder altitude of 2, 400 feet.
五秒钟后，最后的雷达目标显示该飞机的磁航迹为217度，速度131节，应答机高度2400英尺。
In 1960, the FAA began successful testing of a system under which flights in certain positive control areas were required to carry a radar beacon, called a transponder, that identified the aircraft and helped to improve radar performance.
1960年，联邦航空局进行了一项成功的试验，在特定管制空域内的航空器安装了一个称作应答机的雷达信号装置。它能够用于航空器识别并增强雷达的性能。
It is common that pulse radar transponder be used in launch vehicle and weapon system. So the development of intellectualized test about pulse radar transponder is typicall.
由于脉冲雷达应答机为各运载和武器型号所普遍使用，开发其智能化测试系统具有一定的通用性，有利于自动测试方法的进一步普及和推广。
An Applicable Transponder of Airborne Fire-Control Radar
一种通用的机载火控雷达应答机
Furthermore, future application of the newly developed intellectualized test system of pulse radar transponder is discussed.
本文还对该智能化测试系统现阶段的应用情况和运用前景进行了分析。
The pilot then selects the 0220 code on their transponder and the track on the radar screen of the air traffic controller will become correctly associated with their identity.
随后飞行员把应答机的代码设置为0220，这样飞机的身份信息就能正确显示在航空管制的雷达屏幕上。
The first loss of the jet's transponder, which communicates the jet's position, speed and call sign to air traffic control radar, would require disabling a circuit breaker above and behind an overhead panel.
首先被关闭的应答器可向空中交通控制雷达发送飞机位置、速度和呼叫信号，关闭它需要切断顶部仪表板上方和后面的一个断路器。
Maritime radar interrogator transponder
海上雷达询问应答器
Space traveling wave tube (TWT) is the core component of satellite transponder and spaceborne synthetic aperture radar transmitter, Therefore, it is knew as the " heart " of satellite communication systems.
空间行波管是星载转发器和星载合成孔径雷达发射机的核心部件，因此被誉为卫星通讯系统的心脏。
