Adaptive resource management in multiple targets tracking for co-located multiple input multiple outputradar

摘要

Co-located multiple input multiple output (MIMO) radar is one kind of new style radar, whose transmitting waveforms of each sub-array are orthogonal to each other. Compared with phased array radar, its beam width is wider. Therefore, different targets may be illuminated simultaneously with one beam in co-located MIMO radar. An adaptive resource management in tracking for co-located MIMO radar is proposed, where the sub-array number, the illuminated targets set and the transmitting waveform of the system can be controlled. The optimal parameters are chosen according to a cost function that takes both the desired tracking precision and consumed energy into consideration. Simulation results demonstrate the effectiveness of the algorithm. Using the algorithm, co-located MIMO radar can achieve the desired tracking precision with less cost compared with phased array radar.
