3D detection of automobile scattering centers using UWB radar sensors at 24/77 GHz

Rethinking vehicle classification with wide-angle polarimetric SAR

“…Figure 3 shows a 3600 RGB image of one pass of the Gotcha public release data set [8], [9]. Under the Krogager polarization decomposi tion [10] and RGB coloring (2) (3) (4) and red, green, and blue pixels represent scatterers that re flect like a "sphere," "diplane," or "helix," respectively. For this reason, the parked cars in the lower right region of Fig ure 3 appear with a red outer outline and a green inner out line.…”

“…Since the dawning of Britain's Chain Home early warning radar system in the 1930s, radar has become a staple tech nology in commercial and defense sensing systems [1], [2], [3]. Today, advanced microwave transmitters can produce nearly any desired waveform; radio frequency receivers can sense radar echoes amidst many forms of noise, clutter, and interference, and modern signal processing techniques and algorithms can transform gigabits of raw data into near real-time information for civil or defense missions.…”

RCS modeling and measurements for automotive radar applications in the W band

“…The platform used to hold large objects like vehicles is available in very few research laboratories in the world. Only a limited set of reports on RCS simulation and measurements of vehicles and pedestrians in the W band have been reported to date [7]- [9]. The main focus of this work is to investigate car backscattering behavior in millimeter wave bands through simulation and measurements.…”

Optimization of a MIMO radar antenna system for automotive applications

“…In the previous section two important metrics have been mentioned, in particular the AF in (1) and the BP of the virtual array in (2). Both functions could be used for the definition of a proper fitness function.…”

“…In a number of applications, for example the estimation of the contour and orientation of a vehicle, high resolution radar images are required [2], [3]. The Rayleigh criterion [1] relates the angular resolution with the dimension of the sensing element, i.e.…”
