A scanning FMCW-radar system for the detection of fast moving objects

Abstract

This paper describes a mobile broadband 57 GHz -64 GHz FMCW radar sensor system designed to improve the situational awareness of soldiers on peacemaking or peacekeeping missions by detecting projectiles in flight. In order to obtain an instantaneous coverage of the azimuthal field of view, a frequency-scanning meander antenna is used. Thereby, the sensors are provisioned to employ a scanning principle by radiating broadband waveforms with different frequencies into separate spatial directions

Combining 77–81 GHz MIMO FMCW radar with frequency-steered antennas: a case study for 3D target localization

“…The curve exhibits different slopes in the frequency regions of 77.5-78.5, 78.5-79.5, and 79.5-80.5 GHz, indicating distinct tilt rates 𝜕𝜃 𝜕f of the main lobe. The TX antenna itself is expected to demonstrate a linear relationship between the main lobe direction and frequency, as shown in [12]. However, Fig.…”

“…Due to its high bandwidth, this antenna is ideally suited for millimeter wave FMCW radar systems that generate linear frequency chirps. For example, a system for tracking very fast objects [11][12][13] and an imaging radar [14] have been developed based on this antenna.…”

A Software-Synchronization Based, Flexible, Low-Cost FMCW Radar

“…If different modulation waveforms are to be produced, we need to replace the original parts with different parameters, which greatly reduces the flexibility of radar system. In [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], software estimations are used in the analysis of radar echo signals. In [2,3,6] PC is used for software estimation, while in [4,16] MCU is used for the software estimation.…”

On-Body V-Band Leaky-Wave Antenna for Navigation and Safety Applications

“…Of the various sensing modalities, millimeter-wave (mmWave) radars offer a cost-effective, lightweight, and robust sensing solution, since they do not depend on the ambient light conditions and do not affect the user's privacy. In particular, short range frequency-modulated continuous wave (FMCW) radars can be implemented in a compact electronic system due to their low power consumption and low profile [1], [5]. Traditionally these sensors have been placed on rigid objects (e.g., white canes and engineered glasses) which can burden the user [1], [6].…”
