A Low Cost K-band Doppler Radar Sensor for Traffic Control Applications
نویسندگان
چکیده
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 mixer and a simple coupling/duplex configuration; the antenna is realized on a 0.031” thick Rogers 4003 laminate to allow its stand alone operation. The antenna is fed by the module through a unique dual waveguide-to-microstrip transition which is also integrated in the patch antenna design. It is anticipated that this simple low-cost sensor has a more than 100 meters detection range. Index Terms — Doppler, radar, sensor, patch antenna, traffic control, front-end module.

Freeway traffic flow is described in terms of control theory. The detecting elements of millimeter-wave radar sensors, which detect speed and occupancy time by a 61-GHz continuous-wave doppler radar, are used. The regulating unit consists of variable traffic signs for traffic-dependent speed limit and alternative route guidance. The control unit consists of a local computer and a control center...
متن کاملAssessing the performance of SpeedInfo radar traffic sensors
Traffic speed is a crucial input for real-time traffic management applications. Operating agencies typically deploy loop detectors or similar sensors to collect the measurements in house. Recently SpeedInfo emerged with a different paradigm for traffic speed collection: instead of selling hardware to operating agencies, at each link the company deploys their own Doppler radar in a self-containe...

In this paper, a novel shore-based S-band microwave Doppler coherent wave radar (Microwave Ocean Remote SEnsor (MORSE)) is designed to improve wave measurements. Marine radars, which operate in the X band, have been widely used for ocean monitoring because of their low cost, small size and flexibility. However, because of the non-coherent measurements and strong absorption of X-band radio waves...
