A DS-UWB Radar System Using a Short-Length PN Sequence
نویسندگان
چکیده
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 results demonstrate that the proposed DS-UWB radar estimates the distance between the radar and an object with a shorter correlation processing time while providing a better estimation performance compared with the conventional DS-UWB radar systems.

Distance Estimation for Radar Systems Using DS-UWB Signals
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 di...

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...

−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...
