Target separation detection and motion parameter estimation method based on time-varying autoregressive model
The Journal of Engineering
The authors report a target separation detection and motion parameter estimation method based on the time-varying autoregressive (TVAR) model. The TVAR model is used to extract the instantaneous Doppler frequencies of multiple targets or scattering points in a same radar range cell, and the motion parameters are estimated based on the Doppler frequencies at every pulse time in a radar frame. In particular, for coherent multipulse echo signal, the TVAR model is first utilised to extract multipledoi:10.1049/joe.2019.0665 fatcat:btus3ftp2jf4rk5lfmzq4fe2ba
