Variable mean sliding window constant false alarm detection algorithm and storage medium

The embodiment of the invention discloses a variable mean sliding window constant false alarm detection algorithm and a storage medium. The algorithm comprises the steps of dividing a radar signal tobe detected into a plurality of units to be detected; calculating a proportional coefficient [alpha] according to the false alarm probability PFA, wherein [alpha]=-lnPFA; taking the average interference level in the sliding window including the units to be detected as the reference interference power; and constructing a detection threshold expression shown in the description, wherein [alpha] is the proportional coefficient, PFA is the false alarm probability, NF is the number of pre-sliding window units, NE is the number of post-sliding window units, and Xi is the units to be detected, and thelength of the sliding window is the sum of the pre-sliding window units, the units to be detected and the number of the post-sliding window units. The radar echo data is discussed in segments withoutadjusting the proportional
