文摘
- •
A double V-chirp waveform is proposed to suppress false targets.
- •
A combined nonlinear processing is employed to enhance delay-Doppler resolution.
- •
A paraboloid filter can enhance non-center targets' power while keeping resolution.
- •
The Resolution depends on chirps' number, targets position and chirp rates.
- •
Resolution enhancement only sacrifices a little bit detection probability.
