“…In this initial study of IEEE 802.11ad-based radar, we make several typical assumptions for LRR applications: 1) a target vehicle can be represented by a single point model [16] and 2) the location, velocity, and radar cross section of a target vehicle remain constant during a coherent processing interval (CPI) [17]. We also assume full-duplex radar operation due to sufficient isolation and self-interference cancellation provided by the spacing between the TX and the RX arrays, use of efficient circulators [18], TX/RX beamforming [19], and the possibility of further suppression in the digital, analog-circuit, or antenna domains [20].…”

Millimeter-wave (mmWave) radar is widely used in vehicles for applications such as adaptive cruise control and collision avoidance. In this paper, we propose an IEEE 802.11ad-based radar for long-range radar (LRR) applications at the 60 GHz unlicensed band. We exploit the preamble of a single-carrier (SC) physical layer (PHY) frame, which consists of Golay complementary sequences with good correlation properties, as a radar waveform. This system enables a joint waveform for automotive radar and a potential mmWave vehicular communication system based on IEEE 802.11ad, allowing hardware reuse.To formulate an integrated framework of vehicle-to-vehicle (V2V) communication and LRR based on a mmWave consumer wireless local area network (WLAN) standard, we make typical assumptions for LRR applications and incorporate the full duplex radar assumption due to the possibility of sufficient isolation and self-interference cancellation. We develop single-and multi-frame radar receiver algorithms for target detection as well as range and velocity estimation within a coherent processing interval. Our proposed radar processing algorithms leverage channel estimation and time-frequency synchronization techniques used in a conventional IEEE 802.11ad receiver with minimal modifications. Analysis and simulations show that in a single target scenario, a Gbps data rate is achieved simultaneously with cm-level range accuracy and cm/s-level velocity accuracy. The target vehicle is detected with a high probability of detection (>99.9%) at a low false alarm of 10 −6 for an equivalent isotropically radiated power (EIRP) of 43 dBm up to a vehicle separation distance of 200 m.

“…A FMCW-CW combined waveform [3] was proposed to reduce the ghost targets while missed targets still exist easily. Another waveform is Frequency-shift keying (FSK) wave [4]. It provides a high velocity resolution and avoids ghost target but cannot distinguish fixed target or moving targets with same velocity.…”

Frequency modulated continuous wave (FMCW) radar has been widely applied in many fields. Modulated waveform is usually designed to solve the coupling problem of range and velocity in multi-target situation. A FMCW-FSK combined waveform is proposed in this work, which takes the advantages of FMCW waveform and FSK waveform. Compared to the FMCW waveform and FSK waveform, this method can reduce the ghost targets and the missed targets furthest with minor error and less calculation cost.

Radars are general devices for defense, survey & vehicle guidance systems. However the sophisticated design & requirements of costly devices, makes it out of reach to the daily applications. Correlation radars are used as anticollision system for auto -motive applications. Objective of this system is to design simple, cost effective architecture of the correlation radar. As a consequence, this system will reduce accidents and enhance road safety. This paper proposed an approach to make the device simple, cheap & much compatible for the automobiles. As a result, it can be used for automated vehicle derive system as well as collision avoidance system. We are presenting a VHDL design for the correlation radar, which is capable to measure distance, relative speed and angle. The proposed radar uses the two receiver concept to measure the angle of the object. The capability to angle measurement will guide about direction of obstacle and also increases the application area of this correlation radar. Principle of this system is to avoid collision between the equipped vehicle and the one in front, or other kind of obstacles (pedestrians, animals, etc). As a result this radar can replace the existing previous version of radar and improve the road safety.
