Patent ID: 8786490

Claim:
A multiband radar detector calibrator comprising: a microcontroller that comprises a pre-stored values in a database and an algorithm-decision logic; a test procedure comprising a sequence of actions stored into said microcontroller and executed in a precisely timed manner defining an output pattern of a microwave radio signal; a plurality of digital to analog converters, which convert digital signals D OUT from said microcontroller into a plurality of analog signals A OUT ; a plurality of conditioning circuits used to convert said analog signals A OUT into voltage levels V CON ; voltage controlled oscillators equipped with appropriate antennas, which oscillating frequencies are controlled by said voltage levels V CON , and their firing states are controlled via microcontroller signals (F CON1 , F CON2 , F CON3 ) that enable individual variation of output power of said voltage controlled oscillators; and a user interface comprising of a plurality of key switches and a display, that enables selecting and verifying of the test procedures pre-stored within the microcontroller, resulting in a generated signal with a complex pattern comprising separated signals produced from one or more of said voltage controlled oscillators, wherein said test procedure comprises: a) forming a calibration signal or signals with the pattern that increases the power level of said calibration signal by any of the voltage controlled oscillators in time; b) activating previously inactivated voltage controlled oscillators to emulate reflections of the original radar signal; c) interrupting the emission of said calibration signal in step a) to emulate a burst constant wave type of a radar emission; and d) producing the signal that is a combination of any signal form defined in the previous steps b)-c), in order to verify the operation of the radar detector device as it would be used in the field.
