Joint power and beam allocation of opportunistic array radar for multiple target tracking in clutter

Antenna Array Aperture Resource Management of Opportunistic Array Radar for Multiple Target Tracking

“…This work is a further research of the previous work of authors [24] [25]. In reference [24], the authors studied the antenna array aperture resource management of OAR for pattern synthesis.…”

“…Through the predicted target information, we can reasonably allocate the antenna array aperture resource. Reference [25] only researches the allocation of power and beams, and it does not involve the pattern synthesis.…”

Joint Adaptive Sampling Interval and Power Allocation for Maneuvering Target Tracking in a Multiple Opportunistic Array Radar System

“…So far, many studies has been done to enhance the utilization efficiency of a scarce radar resource in the target tracking process [10][11][12][13][14][15][16]. Reference [10] proposes a sensor selection policy for static target location in distributed multiple-radar architectures.…”

“…The previously mentioned work provides us with an opportunity, and helps to deal with the resource management problem. However, this work only considers the resource management problems of a uniform moving target [11][12][13][14][15][16]. In the actual battlefield environment, such a favorable circumstance is always an unrealistic assumption.…”

“…Attributing to the spatially decentralized radars, the azimuth changing rate and target velocity relative to different radars are different. According to Equations (13) and (14), the measurement values of the range, azimuth, and the Doppler shift can all affect the power allocation, i.e., the power allocation is a comprehensive influence of the three elements. Therefore, the power allocation ratios are changed all the time when the target is moved.…”
