“…The combination of measured ranges that do not belong together will lead to ghost-target situations at the output of the quadratic position-fixing stage. Classical way to solve position-estimation problem consisting in data-association and quadratic position-fixing algorithm (usually called the top-down approach) can carry a technical challenge in dense multi-target situations [11]. Because of this, an alternative position-estimation process is chosen for the proposed system.…”

Abstract-The use of heavy machinery is one of the main causes of accidents in sites as warehouses or construction. These vehicles have several blind spots that encumber their maneuvering and create a collision-prone environment. To ensure safety in these situations, an early warning system capable of avoiding these accidents is required. An innovative solution consists of the use of a on-board, low-cost, K-band radar network. The complete system is to operate with a very low false alarm rate (FAR) to avoid unnecessary stops and loss of trust by the driver. In order to fulfill this requirement, a processing chain that rejects false detections is implemented. It is also responsible for joining data from all the subsystems of the network.

“…For an assumed position t taken as a reference, optimal data association can be performed based on a simple minimum-distance calculation. This approach is referred as bottom-up processing [11]. To obtain reference points for assumed target positions, a grid is used over the entire observation area as shown in Fig.…”

“…The presence of multiple targets results in additional problems, such as ghost appearance, changing of target tracks or mutual shielding among people. Ghosts are defined as false targets originating for example in the localization phase when the measured bistatic ranges applied for the target position estimation do not belong to the same target [22]. To avoid ghosts, proper association of data received from all receiving channels needs to be done (e.g.…”

Ultra-wideband (UWB) radars are sensors allowing to track people in critical environments and situations. The results reached by single UWB sensors for such applications have shown that they are able to detect and track a person very well in a single person scenario. However, in multiple moving person scenarios, the ability of a single UWB sensor to detect several persons is usually significantly reduced. This is caused by a mutual shielding among people. In this paper, we will deal with the mutual shielding effect and its impacts, as well as with the methods of improving multiple moving person tracking by UWB radars. Firstly, we will provide a comprehensive description of the mutual shielding effect. Then, based on its analyses, we will state three complementary approaches created by the authors of this paper to reduce its impacts. They include an enhancement of the low-level echo of the targets, radar antenna array positioning at a convenient height, UWB sensor network application and, finally, their mutual combinations. The properties of those approaches will be demonstrated by two experimental measurements aimed at through wall tracking of two and three people, respectively. The results obtained in the experiments will illustrate the mutual shielding effect and the potential of the methods we have proposed to reduce its impacts.

A study of some FMCW radar algorithms for target location at low frequencies

FMCW (frequency‐modulated continuous wave) radar is a simple and inexpensive technique for target location. The resolution is given by the available bandwidth and the directivity of the antenna. Resolution is not a problem at high frequencies, while at low frequencies (the HF and VHF band), and especially for mobile platforms, the required size of the antenna becomes impractical. In order to obtain the bearing of the targets, without relying on directivity, one may use a simple two‐dimensional trilateration method that involves several platforms. Since this approach covers an area, rather than a sector, the range is reduced to some tens of kilometers. The VHF band and a bandwidth below 10 MHz is a good choice if the priority is to reduce radio interference. Fast targets, corresponding to a significant Doppler shift, have not been considered. The problem of ghost targets has been studied for both monostatic and multistatic radar. When there is a confluence of echoes, more bandwidth is required to maintain the accuracy of a few meters that is normally obtained in the simulation.
