Mutil-Component LFM Signal Parameter Estimation Method Using STFT And Zoom-FRFT

四川大学学报. 自然科学版, 2016
Traditional parameter estimation methods of multi-component linear frequency modulation (MLFM) signal based on Fractional Fourier transform (FRFT) could solve neither the satisfactory precision nor the lesser computation cost.

A Deep Learning-Based Method for Detection of Multiple Maneuvering Targets and Parameter Estimation

Remote Sensing
With the rapid development of drone technology, target detection and estimation of radar parameters for maneuvering targets have become crucial. Drones, with their small radar cross-sections and high maneuverability, cause range migration (RM) and ...
