Paper Abstract

The land and rain clutter rejection for radar systems of millimeter band of radiowaves is estimated for some types of the radiated signals (the periodic uncoded pulsed sequence, the pulsed-compression signals, the unmodulated continuous signals and the continuous signals with harmonic frequency modulation). It is shown that the use of periodical uncoded pulsed sequence with unambiguous target range determination is preferable. The use of the complex signals with inpulsed modulation permits to increase the clutter rejection if the signal duration after pulsed compression is less than the uncoded pulse duration. Otherwise the clutter accumulation from the large "lighting" area or volume leads to decreasing of the SCR and increases the clutter power from the sidelobes of the ambiguity function. For the continuous harmonical signal the clutter power from the near zone of radar increases and FM of this signal does not permit to provide the clutter rejection to levels obtained for the pulsed sequence.
