We have developed a maximum likelihood formulation for a joint detection, tracking and association problem. An efficient non‐combinatorial algorithm for this problem is developed in case of strong clutter for radar data. By using an iterative procedure of the dynamic logic process “from vague‐to‐crisp” explained in the paper, the new tracker overcomes the combinat...

Bats are suspected of using predictive tracking in their insect-capture behavior. In Webster and Brazier (1965) they are observed capturing rapidly accelerating moths in the presence of vegetation. This is of interest in the context of sonar-guided behavior in biomimetic robotics. Engineering approaches to that problem often use radar tracking algorithms, particularly various Kalman filters, wh...

This paper focuses on test results from an Airborne Obstacle Tracking system for Unmanned Aerial System (UAS) See and Avoid applications that is based on Particle Filtering algorithm. It performs data fusion of airborne forward looking radar and electro-optical camera by exploiting data gathered during a Sense and Avoid flight experiment at Italian Aerospace Research Centre (CIRA). The develope...

A multiple-target tracking problem for a frequency-modulated continuous-wave (FMCW) radar network is formulated and an integrated track management system is presented to solve the tracking problem in the presence of clutter. The FMCW radar network obtains beat frequency measurements with multiple collocated radars, each transmitting a sequence of chirps. The beat frequency measurements are asso...

Abstract – In simultaneous registration and tracking with multiple radars, measurements from geographically distributed radars must be transmitted to a common location where a multi-input tracker simultaneously estimates registered trajectories and radar biases. However, due to band limited communication links, this architecture is impractical. An alternative is to carry out sensorlevel trackin...

In continuous wave (CW) radar and high pulse repetition frequency pulse-Doppler (HPRF-PD) radar, the interference plus noise sample snapshots are hard to be obtained. The desired signal in the received snapshots makes the LCMV-based adaptive monopulse algorithm sensitive to pattern look direction error. A linearly constrained subarray robust adaptive monopulse algorithm based on main lobe maint...

Simulation and prediction of eigenfrequencies and resonance problems for flexible structures is an important task in disciplines such as robotics and aerospace engineering. However, little effort seems to have been put into the problem dealing with modal analysis of mechatronic systems containing coupled flexible structures and control systems. When, for instance, designing a satellite tracking...

This paper reviews the basic radar requirements for tracking small debris (1 to 10 cm). Based on results of the NASA ORDERACS experiment the frequency and sensitivity of five current world-wide radars collecting debris data are reviewed. An analysis of the tracking errors of these radars is provided. Based on their range, velocity, and angle track errors and search capability, the Russian Don-2...

INTRODUCTION Three-dimensional radar reflectivity data and the algorithms used to help meteorologists interpret these data are extremely important in nowcasting. However, a number of inherent problems arise when tracking thunderstorm cells with 3-dimensional reflectivity. These problems include (1) identifying cells in a complex multi-cellular thunderstorm environment, (2) detecting thunderstor...

We consider a track selection problem for multitarget tracking in a multifunction radar network from a gametheoretic perspective. The problem is formulated as a noncooperative game. The radars are considered to be players in this game with utilities modeled using a proper tracking accuracy criterion and their strategies are the observed targets whose number is known. Initially, for the problem ...
