5. MPD model for radar echo signal of hypersonic targets

Author

Subjects
echo, radar signal processing, pulse compression, pulse frequency modulation, MPD model, radar echo signal, hypersonic targets, stop-and-go model, linear frequency modulation pulse compression, SAG model, moving-in-pulse duration, Engineering (General). Civil engineering (General), TA1-2040
Abstract

The stop-and-go (SAG) model is typically used for echo signal received by the radar using linear frequency modulation pulse compression. In this study, the authors demonstrate that this model is not applicable to hypersonic targets. Instead of SAG model, they present a more realistic echo signal model (moving-in-pulse duration (MPD)) for hypersonic targets. Following that, they evaluate the performances of pulse compression under the SAG and MPD models by theoretical analysis and simulations. They found that the pulse compression gain has an increase of 3 dB by using the MPD model compared with the SAG model in typical cases.
