<p>PURPOSE:To eliminate radar interference signals without erroneous elimination of the target signal due to the level fluctuation without generating inconvenience of non-display between the first two sweeps over the threshold level when a new target signal exists. CONSTITUTION:A radar signal processing device is provided with a level judgement part 101 to make a judgement of the input signal level for every range bin, a level judgement signal memory part 102 to realize consecutive memorization of the level judgement signal of the continuous two sweeps for every range bin, and radar interference judgement means 103, 104 to output the judgement results that the radar interference is made, when in comparison with the level judgement signal for every range bin, a judgement is made that one past sweep exceeds the threshold level, and the present and two past sweeps do not exceed the threshold level. There are in addition provided an input signal memory part 105 to memorize the input signal of one past sweep, and a display signal switching part 106 to output the signal of the same range bin from the input signal memory part 105 as the display signal when no radar interference is made.</p> |
