Research paper thumbnail of Adaptive Algorithm For Tracking Maneuvering Targets In A Complex Jamming Environment For A Radar With Range Rate Measurement

To increase the detection efficiency of moving targets masked by interfering reflections, radars ... more To increase the detection efficiency of moving targets masked by interfering reflections, radars are widely used, in which target spatial coordinates and also range rate are measured. When solving the radar data processing problems, the presence of target range rate measurements increases the target tracking efficiency in the presence of false plots, and can significantly improve the tracking quality, especially with intensive target maneuvering. In the work on the mathematical apparatus basis of the mixed Markov processes in discrete time, a quasi-optimal adaptive algorithm for tracking maneuvering targets in a difficult jamming environment for a multifunctional radar with range rate measurement is developed. Using statistical computer modeling, a comparative analysis of tracking algorithms with and without measurement of range rate in the same interference environment at different data rates is performed.

To neutralize them, complex UAV protection systems are created, which include passive and active measuring systems. As a passive system, a wireless sensor network is used, which allows to determine location of UAV with high accuracy based on TDOA measurements. However, in real conditions, abnormal (rough) measurement results may appear that lead to divergence of Kalman filtering algorithms for UAV movement parameters.On the basis of a mathematical apparatus of the mixed Markov processes in discrete time, a quasi-optimal algorithm of adaptive estimation of UAV movement parameters based on the TDOA-measurement of the sensor network in the presence of abnormal measurement errors was synthesized. The efficiency analysis of obtained algorithm and its comparison with algorithm of Kalman filtering are performed using the statistical simulation..

It acquires special significance at small signal-to-noise ratio. The presence of plots amplitude information allows to increase the efficiency of target detection and target tracking in the presence of interference. In the work a sequential algorithm for target track loss detection using the plots amplitude information based on the Shiryaev rule is obtained. Moreover, the method of probabilistic data association is used to estimate target's movement parameters at small signal-to-noise ratio. The analysis of the obtained algorithm efficiency is performed on a model example of target tracking due to the survey radar which measures range and range rate using statistical modeling.

Using the mathematical apparatus of Kalman filtering, the algorithm is developed, which after forming initial conditions on the basis of determining of radio sources location from one pair of sensors, allows to recurrently determine its location in a rectangular coordinate system as data from other pairs of sensors are received. The efficiency analysis of the algorithm is performed using the statistical simulation. The application of the recurrent algorithm allows to reduce the RMS errors of radio source position estimation by 1.75-6 times.
