Sensitivity time control (STC) factor
Compute the STC factor for the STC cutoff range of
50 km and the STC exponent of
R = 0:1e3:100e3; RC = 50e3; X = 3.0; FSTC = stcfactor(R,RC,X);
Plot the STC factor.

R— Range at which to compute FSTC
Range at which to compute
FSTC, specified as a positive scalar
or length-J vector in meters.
RC— STC cutoff range
STC cutoff range, specified as a positive scalar or as a length-
vector in meters.
X— Exponent to maintain target detectability
Exponent to maintain the target detectability, specified as a positive scalar in the
[3,4] or as a length-K vector with each
element in the range of
[3,4]. The exponent maintains the target
detectability below the STC cutoff range.
