て検出する確率を一定とし、目標を自動検出する
ためのスレツシヨルドを設定する手段とを備えた
ことを特徴とするウエザクラツタ中目標自動検出
装置。 An average value calculation circuit takes the received power from weather clutter (reflected waves from rain, rain clouds, etc.) as an input signal and calculates the average value of this signal, and calculates a threshold based on distance to calculate the probability of mistakenly detecting weather clutter as a target. 1. An automatic target detection device during weather clutter, characterized in that it is provided with means for setting a threshold for automatically detecting a target.
