Design and Processing of a Novel Chaos-Based Stepped Frequency Synthesized Wideband Radar Signal
The linear stepped frequency and linear frequency shift keying (FSK) signal has been widely used in radar systems. However, such linear modulation signals suffer from the range–Doppler coupling that degrades radar multi-target resolution.
