“…In the following, the chirp sequence processing model was applied to the received signals of a monostatic radar sensor [8] with a vertical polarized lens horn antenna with Table I shows the radar sensor parameters. The radar sensor was operating with a starting frequency of 77 GHz and a frequency deviation of 1.5 GHz.…”

Detection of pedestrians in an urban environment is a highly sophisticated task. This paper presents a signal processing technique suitable for frequencymodulated continuous wave (FMCW) radar sensors using chirp sequence modulation, allowing observation of slow-moving objects with high resolution capability in range and velocity. Velocity resolution can be improved through auto-regressive linear prediction (AR-LP) without requiring a long chirp sequence duration. Furthermore, the influence of the frequency deviation used and velocity resolution will be shown in a scenario with two objects. An adaptive velocity resolution improvement will be presented to extract a characteristic micro-Doppler signature (μD-signature) of a slowly moving pedestrian, a car, and an inline-skater. This is verified by measurements at the carrier frequency of 77 GHz.

Traditional constant false alarm rate (CFAR) methods have shown their potential for foreign object debris (FOD) indication. However, the performance of these methods would deteriorate under the complex clutter background in airport scenes. This paper presents a threshold-improved approach based on the cell-averaging clutter-map (CA-CM-) CFAR and tests it on a millimeter-wave (MMW) radar system. Clutter cases are first classified with variability indexes (VIs). In homogeneous background, the threshold is calculated by the student-t-distributed test statistic; under the discontinuous clutter conditions, the threshold is modified according to current VI conditions, in order to address the performance decrease caused by extended clutter edges. Experimental results verify that the chosen targets can be indicated by the t-distributed threshold in homogeneous background. Moreover, effective detection of the obscured targets could also be achieved with significant detectability improvement at extended clutter edges.

“…The detection radars working at 76 GHz or 78GHz for foreign object debris (FOD) detection on airports are now developing [5], [6]. A basic motivation of FOD radar is the fatal accident with a Concorde aircraft in 2000 due to a metal part lost by an aircraft on the runway some minutes before.…”

This paper presents a novel structure of reflectarray element for millimeter-wave reflectarray antennas. The proposed reflectarray element is based on a cut ring patch coupled through an annular slot to a circular patch connected with a variable length line. The reflectarray element is designed for working at 76 GHz. A progressive phase range covering 460 degrees has been achieved by varying the length of microstrip line. The linearity of the reflection phase versus line-length is also reported and improved by modifying parameters of the patches.
