Abstract :
Radio frequency (RF) stealth radar signal waveform design is an important issue in design of modern radar systems. The Costas/PSK radar signal waveform is designed and their RF stealth performance is analyzed. First, the FSK FH and PSK continuous wave radar are introduced differently. Second, the FSK/PSK continuous wave radar is constructed and its performance is analyzed. Lastly, five kinds of different FSK/PSK radar signal waveforms are designed. Their power spectrum density (PSD) is analyzed and simulated. The research results show that the RF stealth performance of combined Costas/PSK signal waveforms is better than Costas signal.
