Target Tracking System Using Passive Radar: A Survey

Most radar systems detect low-level processing of the first received sensor data and transfer the processed data to some higher-level processor (e.g. tracker or classifier) to achieve the computer purpose (target dynamics parameters). Passive radar has the following advantages: (i) no frequency allocation, no radiation, good electromagnetic compatibility, and good concealment; (ii) the obvious advantages of theft and low-altitude detection; (iii) Low growth and maintenance cost, small size, high mobility and easy deployment. Because of these characteristics, special attention was paid to their use in the military and key technologies were developed. Microwave radiation form radar antenna is harmful to operators. Hence antenna removing can address both issues. No study is found to support antenna removing of AESA radar with the help of MWP. Increasing complexity does not reduce erroneous goals that are classified as real goals. No more work on things designed for human safety. Research is needed to understand the harmful effects of lasers on the human body.
