The algorithm is the following: If _positiveRatio_ % of the last _windowDuration_ jammer detection decisions coming from the sensor (in the raw decisions table) are positive and the JNR (Jammer to Noise Ratio) is greater than _jnrThreshold_, then declare a positive attack event. If not, declare a negative attack event.
