    • A transceiver system allows for simultaneous operation of transmit and receive modes, even in shared path configurations, by temporarily making the receiver insensitive to transmitter energy and by modifying standard readout technology to rapidly dissipate any transmitter energy deposited onto the receiver's detector elements. The entirely electronic technique alerts the receiver to the imminent emission of each transmitter pulse. This alert opens a gate voltage switch in the readout and prevents energy that is present on the detector from being passed to the readout integrator. As soon as the transmitter pulse has passed and any charges it generated on the detector have been dissipated, the switch is automatically closed and the receiver is again fully active. Since this on/off switching happens automatically and rapidly it can operate independently from, and have very little impact on the receiver. Furthermore, it levies absolutely no limitations whatsoever on the operation of the transmitter.
    • 收发器系统允许通过临时使接收机对发射机能量不敏感并通过修改标准读出技术来快速耗散沉积在接收机的检测器元件上的任何发射机能量,即使在共享路径配置中也可以同时操作发射和接收模式。 完全电子技术可以使接收器立即发出每个发射器脉冲。 该警报在读数中打开门电压开关,并防止存在于检测器上的能量传递到读出积分器。 一旦发射机脉冲通过并且其在检测器上产生的任何电荷已经消散,则开关自动关闭,并且接收器再次完全有效。 由于该开/关切换自动且快速地发生,它可以独立于操作,并且对接收器的影响很小。 此外,它对发射机的操作绝对没有任何限制。
