Distance Estimation for Radar Systems Using DS-UWB Signals
نویسندگان
چکیده
In this paper, we propose a distance estimation scheme for radar systems using direct sequence ultra wideband (DS-UWB) signals. The proposed distance estimation scheme averages out the noise by accumulating the correlator outputs of the radar, and thus, helps the radar to employ a short-length DS-UWB signal reducing the correlation processing time. Numerical results confirm that the proposed distance estimation scheme provides a better estimation performance and a reduced correlation processing time compared with those of the conventional DS-UWB radars. Keywords—Radar, DS-UWB, distance estimation, correlation accumulation.

A DS-UWB Radar System Using a Short-Length PN Sequence
In this paper, we propose a direct sequence ultra wideband (DS-UWB) radar system using a short-length pseudo noise (PN) sequence. The proposed DS-UWB radar reduces the correlation processing time by averaging out the noise in the correlator outputs, and thus, employs a short-length PN sequence unlike the conventional DS-UWB radar systems using multiple variable-length PN sequences. Numerical re...
متن کامل3-Dimensional Imaging and Motion Estimation Method of Multiple Moving Targets for Multi-Static UWB Radar Using Target Point and Its Normal Vector
Radar systems using ultra-wideband (UWB) signals have definitive advantages in high range resolution. These are suitable for accurate 3-dimensional (3-D) sensing by rescue robots operating in disaster zone settings, where optical sensing is not applicable because of thick smog or high-density gas. For such applications, where no a priori information of target shape and position is given, an acc...
متن کاملA Rapid Distance Measuring Scheme for Ultra Wide-Band Vehicle Radar Systems
This paper proposes a novel distance measuring scheme for ultra wide-band vehicle radar systems. The proposed scheme measures the distance between a vehicle and an obstacle based on repeated use of a single short pseudo random sequence. The numerical results show that the proposed scheme provides a shorter mean distance measuring time while keeping a similar measurement error performance to tha...
متن کاملAn Experimental Study on an Accurate UWB Radar Imaging Method for a Target with Unknown Motion using a Small Number of Antennas
Developing a cost-effective security system has been an important issue in crime prevention. Although cameras have been known as an effective candidate for this purpose, they have some downside, such as difficulty in accurately estimating the three-dimensional shape of a target, and the exact distance to a target [1], [2]. Ultra-wideband (UWB) pulse radar is an alternative for resolving these p...

−This paper studies the interference effects from 4 types of ultra wide band (UWB) sources on a narrowband π/4-shift differential quadrature phase keying (DQPSK) transmission system by simulation. The culprit UWB sources were: multi-band orthogonal frequency-division multiple-access (MB-OFDM), direct-sequence code-division multiple-access (DS-CDMA), DS spread spectrum UWB (DS-SS UWB), and addit...
