• Comparing traffic intensity estimates employing passive acoustic radar and microwave Doppler radar sensor

  Publikacja

  • A. Czyżewski

  - Journal of the Acoustical Society of America - Rok 2020

  The purpose of our applied research project is to develop an autonomous road sign with built-in radar devices of our design. In this paper, we show that it is possible to calibrate the acoustic vector sensor so that it can be used to measure traffic volume and count the vehicles involved in the traffic through the analysis of the noise emitted by them. Signals obtained from a Doppler radar are used as a reference source. Although...

  - Remote Sensing - Rok 2019

  Innovative road signs that can autonomously display the speed limit in cases where the trac situation requires it are under development. The autonomous road sign contains many types of sensors, of which the subject of interest in this article is the Doppler sensor that we have improved and the constructed and calibrated acoustic probe. An algorithm for performing vehicle detection and tracking, as well as vehicle speed measurement,...

• Approximate Cramér–Rao bound on Doppler error in correlation-processing relatively narrowband noise radar

  Publikacja

  • M. Meller

  - IET Radar Sonar and Navigation - Rok 2009

  The paper studies limitations on accuracy of Doppler estimation in continuous-wave noise radar with correlation processing. Second order properties of output of the correlation receiver are evaluated and an approximate Cram´er-Rao bound on errors of Doppler measurement is derived. The accuracy of Doppler measurements is found to be affected by the following factors: power spectral density of noise signal, frequency response of the...

• Radar with rotary head

  Publikacja

  • K. Zubiel

  - Rok 2018

  Nowadays usage of radars is no longer reserved only for the military purpose. It finds many applications in various areas of science and industry. It may be used in order to obtain extended information about the state of critical infrastructure, like shipyards or petrochemical plants. Furthermore, it may be applied in vision denied environments. The aim of this project...

  • M. Młynarczuk

  - Zeszyty Naukowe Akademii Marynarki Wojennej - Rok 2019

  The main task of the Polish Border Guard is protection of the country’s border which requires utilization of multimedia surveillance systems automatically gathering, processing and sharing various data. The paper presents such a system developed for the Maritime Division of the Polish Border Guard within the STRADAR project and the problem of fusion of radar data in this system. The system, apart from providing communication means,...

• A concept of software extension of 3D low-PRF radar systems to 4D semi-medium-PRF radar systems

  Publikacja

  • M. Meller
  • K. Stawiarski

  - Proceedings of SPIE - Rok 2019

  We present a concept of software modification of three-dimensional (3D) radar systems, designed to work in the low pulse repetition frequency mode, that equips them with the ability to estimate the radial velocity and to properly measure the range of targets that are detected outside the radar’s instrumented range. Despite the fact that the proposed modifications are designed so as to require only minor changes in software, they...
