This paper discusses the operating range of frequency modulated (FM) radars in the presence of interference. For this purpose, radar- and path loss equations are used to draw the equipotential lines for a given signal-to-interference ratio as a function of the spatial distribution of targets and interferers in order to identify relevant scenario constellations. Further the factors influencing the gain of signal versus deterministic interference are discussed based on measurements and simulations. Finally, the influence of different kinds of interference on the spectrum of a frequency modulated continuous wave radar is shown.

“…The FPGA module is placed at the bottom of the hardware stack. The realized system architecture is divided into a function block for time-sensitive operations, implemented by the hardware description language VHDL and an embedded soft-core processor design as presented in [17]. The switching of the transmitter channels and the protocol handling of the ADC are implemented as VHDL modules in order to meet the timing and clock requirements.…”

“…For the acquisition of the angular information in azimuth and elevation, the transmit and receive antenna arrays are arranged orthogonal to each other [10, 11]. The combination of the so-called T-shaped antenna array arrangement with the multiple-input multiple-output (MIMO) technique is an advantageous method for two-dimensional beamforming [12, 13].…”

This paper introduces a radar system for three-dimensional (3D) object detection and imaging. The presented 3D measurement method combines the frequency-modulated continuous wave (FMCW) approach for range measurements with a multiple-input multiple-output (MIMO) technique for digital beamforming in two dimensions. With an orthogonal arrangement of the antenna arrays for transmit and receive, the angular information is obtained in azimuth and elevation without mechanical beamsteering. The proposed principle allows performing 3D imaging by means of the acquired range, azimuth, and elevation information with a minimum of required hardware. Starting from the realization of the 3D radar imaging concept, the hardware architecture and the developed prototype are discussed in detail. Furthermore, the object detection capability of the 3D imaging radar system is demonstrated by measurements. The results show that the introduced 3D measurement concept in its realization is well suited for numerous applications.

“…These wide-angle scanning antennas are not suitable for K-band radar sensor because of their large size or fabricating complexity. Patch antenna possesses the low profile but cannot easily achieve the wide-angle beam scanning due to its narrow beam width [14]- [16]. For instance, the traditional patch antenna array for radar system proposed by [15] can achieve a beam scanning only within ±45 • .…”

In this paper, a K-band antenna with ±60 • beam scanning is proposed for a mmWave (millimeter-Wave) radar sensor. Especially, we take advantages of the magnetic dipole principle, and design the antenna by employing via holes in three sides, so as to form a cavity which can be equivalently considered as magnetic dipole, resulting in the 3 dB beam width as wide as 140 • in E-plane. We cascade the mmWave antenna to 1×4 and 4×4 arrays for radar transmitting and receiving, respectively. The antenna array is fabricated and implemented to a K-band radar and its wide-angle beam scanning performance is evaluated by the radar's distance and angular detections.
