"In spite of the positive results obtained, it should be pointed out that there is still a need for further studies and improvements," researchers say. "A future study could include implementing advanced signal processing algorithms for improving detection accuracy. Furthermore, more experiments could be conducted for investigating the system's capability for detecting and tracking of moving targets at a very low speed and low target profile."
