2020年10月24日 · Abstract: A CMOS K-band impulse generator for UWB radar IC is presented. To provide the short UWB impulse signal, a carrier-based impulse generator is employed, which combines the VCO and active RF switch for windowing the LO signal.

In this paper, a K-band antenna with ±60° beam scanning is proposed for a mmWave (millimeter-Wave) radar sensor. Especially, we take advantages of the magnetic dipole principle, and design the antenna by employing via holes in three sides, so as to form a cavity which can be equivalently considered as magnetic dipole, resulting in the 3 dB ...

The DF300 sensor belongs to the DF-series K-band sensors designed specifically for long range traffic applications. They are the ideal RF-frontend to provide precise speed measurements via 2 analog quadrature channels. With the highest internal gain among the DF-series, the DF300 provides the best-in-class range and precision.

The AP81 sensor belongs to the AP8-series K-band sensors designed for general mid-range applications. The design optimizes range, detection angle and cost in a low profile package. Designed with dual-channels, the AP8-series sensors are able to discriminate target direction.

Abstract — A low-cost short-range K-band Doppler radar sensor for traffic control applications has been developed. The compact sensor, including a waveguide front-end module and a planar patch antenna, weighs only 0.1 lb. The module incorporates a Gunn oscillator, a …

K Band Radar operates at frequencies between 18 GHz and 27 GHz, making it ideal for short – range detection. It is commonly used by law enforcement officers to measure vehicle speed and enforce traffic laws. K Band Radar is also utilized in collision avoidance systems, weather monitoring, air traffic control, and military applications.

2025年1月22日 · This paper presents a novel K-Band Quadrature Phase Shift Keying (QPSK) phase-modulated continuous-wave (PMCW) radar front end architecture with digital I/Q constellation phase compensation and I/Q channel imbalance correction. Although QPSK is a very common form of digital phase modulation, it is rarely reported for PMCW radar systems, especially those designed on printed circuit board (PCB ...
