Abstract :
In the high resolution radar theory, a lot of powerful sidelobes reduction techniques are indicated. Belonging to this major research direction, the goal of this paper is to present some theoretical and experimental results achieved by applying on a LFM radio pulse with the low values of the basis, of the temporal frequency predistortioning techniques at the pulse ends using two proper nonlinear laws. Finally, some aspects concerning the optimization of the parameters assigned to the proposed frequency predistortioning laws are also discussed.
