We extend our recent findings regarding various antenna mounting positions, analysing a typical rural street traffic scenario. Varying antenna characteristics are evaluated regarding their communication and sensor suitability to address future intelligent transportation systems based on joint radar-communications. The mirror position with a 16x16 patch array is recommended, whereas for the bumper and the roof less focused antennas like a 4x4 patch array are recommended.

This paper demonstrates a squaring circuit, which is a key element in many low-power receivers, designed in a low-cost technology. For its functionality, the circuit exploits the typical characteristics of a transistor. To enhance the speed of the circuit and consequently to enable higher data rates for the receiver, a novel “boosting circuit” is implemented. An additional control circuit regulates the output and simplifies the detection of an incoming signal.

This paper presents a guided wave Six-Port interferometric radar system with integrated I/Q offset cancelation. An intelligent algorithm is proposed which optimally adjusts three voltage controlled attenuators and one voltage controlled phase shifter in the radio frequency part of the system. By minimizing the I/Q offset, the standard deviation as well as the relative error are decreased in comparison to an uncompensated measurement setup.
