    • The invention discloses the laser transponder system for disrupting speed and/or distance measuring LIDARs. The system consists of at least two laser transponders 101, 102, a microcontroller 103 and a user interface 104. The microcontroller 103 is connected to both laser transponders 101, 102, and to the user interface 104. Microcontroller 103 is analysing input from laser transponders 101, 102, and is determining their output. In case an advanced speed measuring LIDAR signal is detected the microcontroller 103 configures first laser transponder 101 as a transmitting only unit 101B and second laser transponder 102 as a receiving only unit 102B. Transmissions emanating from the transmitting only unit 101B are not received by the receiving only unit 102B. Disrupting signal periods are selected by the microcontroller 103 algorithm from its pre-stored database according to a detected LIDAR signal. Novelties of the invention are that the disrupting signal is transmitted simultaneously with synchronizing a disruption timer for the next period of a disrupting signal and that multiple disruption signal periods are timed in parallel on a given synchronization event. That way all speed measuring pulses of a LIDAR signal are disrupted even in the case of an advanced speed measuring LIDAR with a random pulse repetition rate. An additional novelty of the invention is that the laser transponders 101, 102, have a laser receiver with an adjustable gain controlled by the microcontroller 103, and that the microcontroller 103 algorithm discovers a maximum level of receiving only transponder 102B receiver sensitivity on which there is no echo triggering on transmissions emanating from the transmitting only transponder 101B.
    • 本发明公开了用于破坏速度和/或距离测量激光雷达的激光转发器系统。 该系统由至少两个激光转发器101,102,微控制器103和用户接口104组成。微控制器103连接到激光转发器101,102和用户接口104.微控制器103正在分析来自激光转发器 101,102,并且正在确定它们的输出。 在检测到高级速度测量LIDAR信号的情况下,微控制器103将第一激光转发器101配置为只发送单元101B和第二激光转发器102作为仅接收单元102B。 仅从发送单元101B发出的传输不被接收单元102B接收。 根据检测到的LIDAR信号,微控制器103算法从其预先存储的数据库中选择中断信号周期。 本发明的新颖之处在于,在中断信号的下一个周期的同步中断同时传输中断信号,并且在给定的同步事件上并行定时多个中断信号周期。 这样即使在具有随机脉冲重复率的高速测量LIDAR的情况下,LIDAR信号的所有速度测量脉冲都会中断。 本发明的另一个新颖之处在于,激光转发器101,102具有由微控制器103控制的具有可调节增益的激光接收器,并且微控制器103算法发现仅接收应答器102B接收机灵敏度的最大级别,其中存在 在仅发射应答器101B发出的传输上没有回波触发。
