Abstract :
The range variant bistatic deformation term of LBF is analyzed. By linearizing the difference between the nearest ranges of transmitter and receiver, the range variant bistatic deformation term is approximated as the linear function of nearest ranges summation. Based on this, the new interpolation function is presented. Then the range variant bistatic deformation is compensated by interpolation, this processing is more efficient without blockwise in range blocks. The simulation results prove its effectiveness.
