Automotive engineers are repeatedly faced with the issue of choosing radars with the best angular resolution while having reduced processing times. In this paper, a novel extrapolation method is presented to estimate the amplitudes and phases for virtual antenna elements at the receiver periphery. This method has shown to resolve two targets...

In this article a novel waveform, Random SlowTime Code Division Multiple Access (ST-CDMA) for MIMO radar is presented and investigated. ST-CDMA means that the waveforms of the different transmitters are orthogonal per burst, while conventional CDMA implies orthogonal waveforms of the different transmitters per pulse. In particular, the Doppler...

In a phased array radar which uses Multiple Input Multiple Output (MIMO) techniques, each (group of) element(s) transmits a different waveform. This extra degree of freedom in the design of a phased array radar potentially yields an advantage for improved suppression of sidelobe clutter and jamming. In this paper a Space-Time Block Coding (STBC)...

A coherent two-dimensional (2D) multiple signal classification (MUSIC) processing for the simultaneous estimation of angular and range target positions has been presented. A 2D spatial smoothing technique is also introduced to cope with the coherent behaviour of the received echoes, which may result in a rank deficiency of the signals covariance...

In this paper, a new signal processing technique for Multiple-Input Multiple-Output (MIMO) image processing of a Linear Frequency-Modulated Continuous Wave (LFMCW) automotive radar was developed. The image is the range-speed-direction data cube. The technique comprises two improvements to the standard MIMO image processing: 1) A fast unambiguous...

The authors present a 2D-MUSIC processing for the simultaneousestimation of angular and range target positions. A2D spatial smoothing technique is also introduced in orderto cope with the coherent behavior of the received echoes, which may result in a rank deficiency of the signals covariancematrix. The algorithm is analyzed with respect to its...

In this paper we present a technique to estimate the calibration coefficients of a coherent Multiple-Input Multiple-Output (MIMO) array radar built on a printed circuit board (PCB). Due to the integrated structure and the MIMO nature of the system, a direct measurement of each antenna element behavior cannot be performed. The proposed method is...

In this paper the authors analyze the use of Time Division Multiple Access (TDMA) applied to coherent Multiple-Input Multiple-Output (MIMO) radar systems. One of the main limitations in exploiting the orthogonal condition in the time domain for MIMO radars is the reduction of the unambiguous Doppler interval. With respect to frequency modulated...

The paper presents different processing schemes that have been investigated in order to evaluate the direction of arrival (DOA) with a multiple-input multiple-output (MIMO) radar. Conventional digital beam forming (DBF) and super resolution algorithm (MUSIC) have been applied. The results provided by them have been compared with a compressive...

Multiple-input-multiple-output (MIMO) processing is a consolidated technique in communication systems thanks to the benefits that it offers in multipath fading environments. In recent years, studies have shown how the performances of conventional phased-array radar can be improved by using the same approach. This letter illustrates how the...

In this paper, four different array radar concepts are compared: pencil beam, floodlight, monostatic MIMO, and multistatic MIMO. The array radar concepts show an increase in complexity accompanied by an increase in diversity. The comparison between the radar concepts is made by investigating the detection performance for a surveillance task in...
