New emerging technologies allow to design a radar that is physically undetectable. Their primary use is in the military applications where it is important to avoid detection by the enemy. However, the 'war' of measures and countermeasures goes on also in the area of police speed-measuring radar. If the driver is able to detect a police radar, he will 'safely' break the limits when no radar is present. As the radar detector devices are becoming more and more popular, the effectiveness of speed limit enforcement is diminishing. The paper presents a concept of passive bistatic police radar using existing transmitters as illuminators of opportunity. It is assumed that the signal of UMTS cellular telephony is used because of its increasing coverage and relatively high carrier frequency. The proposed system is analyzed from geometry, power budget and signal processing point of view. The concept of the radar is verified by means of computer simulation using a synthetic baseband UMTS signal.
