“…First, communication between the radars is fast enough to ensure appropriate information sharing. Communication connections using satellites or terrestrial optical cables should be a prerequisite.Second, since numerous researches have been conducted on sensor fusion and data association techniques for the handover of ballistic target information [23,24,27,28,29,30], it is regarded that the targets are handed over smoothly, and filtering problems related to target processing and sensor fusion that occurs are not covered in this study. The methodological and technical problems that may arise in the process of handing over targets between radars are not discussed.…”

“…However, still the aforementioned studies do not contain a methodology for mathematical optimization considering the handover. The research most closely related to target handover for seamless tracking are studies on track to track correlation between the radar track and onboard IR track picture [23]. According to Lewis and Tabaczynski [24], handover technology was first achieved in 2003 between radars, and RF-to-RF and RF-to-IR handover was achieved in 2005.…”

This paper proposes a binary linear programming formulation for multiple target assignment of a radar network and demonstrates its applicability to obtain optimal solutions using an off-the-shelf mixed-integer linear programming solver. The goal of radar resource scheduling in this paper is to assign the maximum number of targets by handing over targets between networked radar systems to overcome physical limitations such as the detection range and simultaneous tracking capability of each radar. To achieve this, time windows are generated considering the relation between each radar and target considering incoming target information. Numerical experiments using a local-scale simulation were performed to verify the functionality of the formulation and a sensitivity analysis was conducted to identify the trend of the results with respect to several parameters. Additional experiments performed for a large-scale (battlefield) scenario confirmed that the proposed formulation is valid and applicable for hundreds of targets and corresponding radar network systems composed of five distributed radars. The performance of the scheduling solutions using the proposed formulation was better than that of the general greedy algorithm as a heuristic approach in terms of objective value as well as the number of handovers.

“…In general, the multiradar fusion mode can be divided into several categories, such as centralized fusion [16]- [18], distributive (distributed) fusion [19]- [25], bistatic processing [26], [27], and passive location [28], [29]. Among these, the distributive radar fusion (or distributed tracking) is the most important and commonly used type of information fusion.…”

Deception Approach to Track-to-Track Radar Fusion Using Noncoherent Dual-Source Jamming

Dual-source jamming is an effective way to prevent monopulse radar systems from performing accurate angle measurements. In this investigation, based on noncoherent dual-source jamming, we propose a cooperative deception approach, which has the benefit of causing persistent and large angular measurement errors to protect a true target and therefore can greatly reduce the discrimination capability of a distributed track-to-track radar fusion system. A scenario involving a single target accompanied by a digital radio frequency memory (DRFM)-based repeater jammer countering two radar systems is illustrated. By controlling the amplitude ratio and time delay in a statistical manner, the active decoy signal and target echo signal can form a noncoherent angular glint effect and result in the deviation of the angle tracking loop of the two radar systems from the true target in opposite directions. The track-to-track association distance related to the retransmission parameters is explicitly derived, and its statistical characteristics are analyzed in detail. Simulations verify the feasibility of the approach. The advantage of the approach lies in its ability to destroy the so-called ''common origin'' signature of the physical target by injecting false angular information. The direct result is that the true target might not successfully complete the process of track-to-track association, thereby enabling us to realize the desirable effect of ''disguise the true target and instead show false decoys''.
