Review on Low Intercept Radar Signal Design Technology

Radar is the key equipment to obtain battlefield situation. Therefore, radar is vulnerable to electronic attack. Low intercept radar can improve the electronic defense capability of radar fundamentally and is a hotspot of radar research. One of the key research fields of RF stealth radar is signal design. First, the concept of low intercept radar is described in this paper. Then, the simple and classical multi-signal system composite modulation technology is summarized. Finally, the development direction of signal design technology is prospected.
