There are three sigma symbols, an upper case, a lower case and an end of the sentence case.
The capital letter case is used as summation.
The lower case is used to represent variance in statistics.
The lower case is also used to represent stress in mechanics and physics.
The end of sentence case is generally not used.

You probably mean the Greek letter sigma since this is the probability area.Lower-case sigma is usually reserved to represent a population standard deviation. When it is squared it represents a population variance. With a caret ('hat') over it it represents an estimator of the population standard deviation.Upper-case sigma is most often used to mean summation (adding up) of terms given by the expression after the sigma. The limits of summation are given above and below the sigma symbol in terms of one of the variables in the expression.
It is the lower case sigma, s, from the Greek alhphabet.It is the lower case sigma, s, from the Greek alhphabet.It is the lower case sigma, s, from the Greek alhphabet.It is the lower case sigma, s, from the Greek alhphabet.
It means the sum total.

The sigma symbol represents the lowest possible radar return signature.

Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.
It is a sigma... it is basically just the Greek version of an S.
