The procedures are as follows: (a) Data initialization: define fuzzy clustering set as c = 2 and optimized classification threshold as ε = 0.3, initialized detection machine number as n, minimum detection frequency of low-risk data as l min, maximum detection frequency of high-risk data as l max, time intervals as Δt.
The maximum detection bistatic range is 14 km, and the minimum detection bistatic range is 1 km, as well as the maximum bistatic range rate 50 m/s and minimum bistatic range rate −50 m/s, and the number of clutter measurements follows a Poisson distribution and the clutter measurements are assumed to be uniformly distributed in this bistatic range and bistatic range rate surveillance space.
Comparison of maximum detection ranges suggests that detection probabilities of small insects are indeed rather similar across bats.
BioMax MS Films (Kodak) were used for maximum detection.
For maxima detection, we imposed a minimum maxima-to-maxima distance criterion of 10 mm.
So, for example, during a 60 second period, each transmitter will have two 20- second aural-code broadcasting periods and two 8 second breaks, meaning that the maximum possible number of detections per minute for each transmitter is ca. 10.
Based on the available s max, we terminate the detection by determining a maximum iteration number iter max.
Hence, in order to detect a maximum number of elementary cycles in a limited amount of time, we use one of the most efficient cycle detection methods, namely Johnson's algorithm [ 38].
This dictionary helped in error detection and correction by providing lexical coverage and the maximum the number of words that can be included in a word list from which to choose the correction for a misspelled word.
The criteria for peak detection were: signal/noise ratio >5.2 Da peak width filter, and maximum peak number of 200.
