“…Note that, the preliminary value of W and L are not the actually value for the final use, they should be modified through simulation. The width W of the radiating patch might be smaller or larger than the value obtained from equation (1). If W is smaller, the gain and BW will decrease, however, the W can't be too large, which would excite the higher order modes.…”

“…The W can be derived by the equation as follows [4], (1) where c is the velocity of light in free space, f 0 is the resonant frequency, ɛ r is the relative permittivity. We defined the resonant frequency as the central frequency of the radar, which is 24.125GHz.…”

“…A lot of research and products have been made in the past years, which mainly focused on the Advanced Driving Assistant System (ADAS), autonomous driving technologies, environmental sensors and intelligent connected vehicles. The conventional sensors are divided into two aspects, one is the electro optic (cameras and lidar) sensors, and another is the electromagnetic (radars) sensors [1].…”

A 24GHz multi-function assist system has been developed for advanced automotive radar, which includes different applications in Blind Spot Detection (BSD), Lane Change Assist (LCA), Doors Open Warning (DOW) and Rear Cross Traffic Alert (RCTA). The multi-function radar is based on the micro-strip antenna, which has a reasonable design on main-lobe and side-lobes. According the antenna, the radar can operate in mid-range mode with a high gain and a narrow beam width, whilst performing well in short-range and wide-angle mode.

The necess bandwidth for a specific range resolution ∆r can be deri from ∆r = c 0 /(2∆f ), where c 0 is the speed of light and is the absolute bandwidth.…”

Abstract. Machine damage due to tool collisions is a widespread issue in milling production. These collisions are typically caused by human errors. A solution for this problem is proposed based on a low-complexity 24 GHz continuous wave (CW) radar system. The developed monitoring system is able to detect moving objects by evaluating the Doppler shift. It combines incoherent information from several spatially distributed Doppler sensors and estimates the distance between an object and the sensors. The specially designed compact prototype contains up to five radar sensor modules and amplifiers yet fits into the limited available space. In this first approach we concentrate on the Doppler-based positioning of a single moving target. The recorded signals are preprocessed in order to remove noise and interference from the machinery hall. We conducted and processed system measurements with this prototype. The Doppler frequency estimation and the object position obtained after signal conditioning and processing with the developed algorithm were in good agreement with the reference coordinates provided by the machine's control unit.

“…By now, the focus in the development of automotive radar sensors mainly lies in the allocated frequency bands at 76-77 GHz for long-range radar (LRR) [2] and 77-81 GHz for short-range radar (SRR) [3]. To achieve a high angular resolution, digital beamforming (DBF) concepts are expected to be used in future systems [1], [4], [5].…”

Abstract-An antenna concept for compact millimeter-wave radar sensors that desire a fan-beam radiation pattern is proposed. It combines an end-fire antenna on a ceramic substrate with a cylindrical parabolic reflector that can be integrated in the sensor's metal housing. The concept allows a direct interconnection from the active components to the antenna in a flip-chip attachment. It is validated with a 77-GHz Yagi-Uda antenna on a 127-m thick Alumina substrate by measurements with a probe-based measurement setup. The measured return loss, gain, and radiation patterns of the antenna without and with the reflector are given.Index Terms-End-fire antennas, millimeter-wave antennas, millimeter-wave radar, radar antennas, reflector antennas.
