Trend of Advanced Radar Technology

Towards digital and multiple-input multiple output (MIMO) configurations leading to

robust systems that can adapt to the environment to coexist with other emitters, improve target detection, achieve higher

resolution, lower measurement errors and enhance tracking, classification and

recognition performance.
