“…For example for 300 Km/h we can have a good detection (P D ≥ 0.9) from a minimum SN R = −15 dB otherwise for 5 Km/h we can have a good detection (P D ≥ 0.9) from a minimum SN R = −45 dB. We can modify the receiver by adding some blocks to determine M = M max adaptively by using the equation (21) and the estimation of v r , Figure 15. But this version does not match with our system as it is not able to goodly estimate the velocity .…”

“…In our study we take N = 1023 that represents the compromise between good performances and less complexity. In fact, this length ensures a high SNR gain (G dB = 30 dB), the correlation complexity is fairly reasonable for an implementation in real time [21]. Also, if we increase the code frequency, we get a good precision in distance.…”

Abstract-The use of Constant False Alarm Coded Anticollision Radar (CFACAR) is very interesting in automotive environment. Due to the orthogonality properties of used codes this system is most robust to multi-user interferences. The actual version of the receiver called in this paper Single Correlation Receiver (SCR), is not able to detect the targets in very low input Signal to Noise Ratio (SN R). To resolve this problem, we present a new receiver called Averaging Correlation Receiver (ACR), that computes the average of the M later correlations. Then, we developed the expression of detection and false alarm probabilities for the new receiver in mono and multi-user scenarios. These probabilities are used to plot the new Receiver Operating Characteristics (ROCs). They are drawn for different values of input SN R and length M of ACR. There is a suitable value of M , according to some equation, that can be taken to have a good detection (ROCs more perfect). Also, we found that for a fixed SN R, we must increase sufficiently the length M but it is possible only for low relative velocity of the target. For a velocity of 5 Km/h with M = 1055, we can lessen the value of the SN R until we reach SN R = −45 dB.

“…The radar consists of two antennas; and emits a signal modulated with a Pseudo Random Binary Sequence (PRBS), resulting in formation of a reference code (Quadri, Elhillali, Meftali & Dekeyser 2009). The PRBS has interesting correlation as well intercorrelation characteristics (Douadi et al 2008). When the transmitted wave encounters an obstacle, it is reflected and creates an echo which is captured by means of the second antenna.…”

Abstract:As SoC design complexity is escalating to new heights, there is a critical need to find adequate approaches and tools for handling SoC co-design aspects. Additionally, modern reconfigurable SoCs offer advantages over classical SoCs as they integrate adaptivity features to cope with mutable design requirements and environment needs. This paper presents a novel approach for addressing system adaptivity and reconfigurability. A generic model of reactive control is presented in a SoC co-design framework: Gaspard2. Afterwards, control integration at different levels of the framework is illustrated for both functional specification and FPGA synthesis. The presented works are based on Model-Driven Engineering and the UML MARTE profile proposed by Object Management Group, for modeling and analysis of real-time embedded systems. Our contributions thus relate to presenting a complete design flow to move from high level MARTE models to automatic code generation, for implementation of dynamically reconfigurable SoCs.

“…Using radar echo to detect pedestrian has its advantage in longer detection range, better position resolution and compatible to various road and weather conditions [1] [2]. The 76-77 GHz band has been designated by the FCC, the ITU in Europe, and by the Ministry of Internal Affairs and Communications (MIC) in Japan for vehicular radar due to its better spatial resolution and longer range in detecting objects compared to other vehicular radar systems operating at lower frequency bands.…”

This paper discusses about the findings of a radar cross section (RCS) study of human at 76-77 GHz based on full-wave numerical model simulations. The trade-off between simulation accuracy and computation efficiency is discussed. In general, simulating full-body scattering at 76-77 GHz requires a fairly large computation resource (memory and CPU time) due to the large size of average human in terms of wavelength as well as many different geometries of different body parts. Measurement RCS pattern is included to verify the accuracy of the simulation model. This study may provide clues to develop unique radar signatures of pedestrian at 76-77 GHz.
