The ability to detect the presence as well as classify the activities of individuals behind visually obscuring structures is of significant benefit to police, security and emergency services in many situations. This paper presents the analysis from a series of experimental results generated using a through-the-wall (TTW) Frequency Modulated Continuous Wave (FMCW) C-Band radar system named Sopra...

This paper is concerned with the Simultaneous Localization And Mapping (SLAM) problem using data obtained from a microwave radar sensor. The radar scanner is based on Frequency Modulated Continuous Wave (FMCW) technology. In order to meet the needs of radar image analysis complexity, a trajectoryoriented EKF-SLAM technique using data from a 360◦ field of view radar sensor has been developed. Th...

In this letter, we introduce a design consideration for super-Nyquist FMCW radar systems relating to transmitter to receiver noise leakage. Phase noise curves comparing the fundamental DDS frequency and its 2nd super-Nyquist image show a significant increase in relative noise level at all offsets from the carrier. This results in a reduced transmitter signal-to-noise ratio. It is shown with a s...

This paper describes the waveform analysis for an experimental long-range (10 Km) high-resolution (1x1 m2) Synthetic Aperture Radar (SAR) sensor in the millimetre wave band on board UAV. Motivated by the need to minimize the transmitted power and the volume filled by the sensor, it is proposed the use of a FMICW (Frequency Modulated Interrupted Continuous Wave) radar type. It also is provided a...

The safety and security of the passengers in vehicles face cyber attacks is a key concern automotive industry, especially with emergence Advanced driver assistance systems vast improvement autonomous vehicles. Such platforms use various sensors, including cameras, LiDAR mmWave radar. These sensors themselves may present potential hazard if exploited by an attacker. In this paper we propose syst...

The application of imaging radar to microwave level gauging represents a prospect of increasing the reliability of target detection. The aperture size of the used sensor determines the underlying azimuthal resolution. In consequence, when FMCW-based multistatic radar (FMCW: frequency modulated continuous wave) is used, the number of antennas dictates this essential property of an imaging system...

For an automotive pedestrian detection radar system, fast-ramp based 2D range-Doppler Frequency Modulated Continuous Wave (FMCW) radar is effective for distinguishing between moving targets and unwanted clutter. However, when a weak moving target such as a pedestrian exists together with strong clutter, the pedestrian may be masked by the side-lobe of the clutter even though they are notably se...

This paper is addressed to a design of K-band dual mode radar used in traffic information collection. The radar can work in both Frequency Modulate Continual Wave (FMCW) mode and Continual Wave (CW) mode. As VCO is seldom used as the oscillator in CW radar for velocity measurement, this paper studied the effect of phase noise and detecting distance on velocity error in CW mode in VCO design. Th...
