Radar High-Speed Moving Target Coherent Integration and Parameter Estimation Algorithm Using PSA-FAIR-NUFFT

With the extension of signal accumulation time, high-speed and low-radar-cross-section (RCS) aerial vehicles cause serious range cell migration (RCM) and Doppler frequency migration (DFM) in radar echoes, significantly degrading radar detection performance. To address the challenge of weak target de...
