摘要:
A pulsed-laser beam detector with improved sun and temperature compensation. The detector includes a plurality of photo detectors, an ambient temperature sensor, a sun exposure filter and a mirroring circuit, a microcontroller unit that includes pre-stored values in a database and an algorithm—decision logic, a time base circuit that feeds microcontroller, an adjustable gain amplifier, a threshold setting circuit, a peak detector circuit, a comparator circuit, and a noise cancellation circuit. The gain of the amplifier is adjustable in real time to predetermined values, and the gain depends on the measured values from the detectors, and temperature sensor, that are preprocessed if necessary, and compared with the values already stored in the microcontroller unit and subjected to the program logic stored in the microcontroller that determines the gain of the amplifier.
摘要:
A laser transponder system for disrupting speed and/or distance measuring LIDARs. The system includes at least two laser transponders, a microcontroller and a user interface. The microcontroller is connected to both laser transponders, and to the user interface. Microcontroller analyzes input from the laser transponders and determines their output. In case an advanced speed measuring LIDAR signal is detected the microcontroller configures the first laser transponder as a transmitting only unit and the second laser transponder as a receiving only unit. Transmissions emanating from the transmitting only unit are not received by the receiving only unit. Disrupting signal periods are selected by the microcontroller algorithm from its pre-stored database according to a detected LIDAR signal. The disrupting signal is transmitted simultaneously with synchronizing a disruption timer for the next period of a disrupting signal and multiple disruption signal periods are timed in parallel on a given synchronization event.

The invention discloses the multiband radar detector calibrator. The calibrator includes a user interface with a keypad and a display, a microcontroller unit that includes pre-stored values in the database and the algorithm—decision logic, digital to analog converter, signal conditioning circuit and voltage controlled oscillators, with their appropriate antennas. The core of invention is the generation of a calibrating microwave signal which resembles the microwave input that a radar detector device would receive in an encounter with a radar device in the field.
