On the example of a fluctuating radar signal acquisition characteristics obtained for a receiver, based on the two-sided contrast method, it is shown that for a threshold contrast values z > 1 two-sided contrast method possesses parametric properties, providing unbiasedness, invariance and similarity, i.e. independence of false alarm probability from a priory unknown power of noise interference. Provided the number of contrast elements m ≥ 10 the receiver has interference immunity approximate to optimal and provides high noise immunity towards the impact of chaotic impulse interference with a priory unknown characteristics.
