. By default,
for each falsealarm probability, the detection probabilities are
computed for 101 equally spaced SNR values between 0 and 20 dB. The
ROC curve is constructed assuming a single pulse in coherent receiver
with a nonfluctuating target.

commaseparated pairs of Name,Value
arguments. Name
is
the argument name and Value
is the corresponding value.
Name
must appear inside quotes. You can specify several name and value
pair arguments in any order as

Minimum SNR to include in the ROC calculation. Default: 

Number of SNR values to use when calculating the ROC curves.

This property specifies the type of received signal or, equivalently,
the probability density functions (PDF) used to compute the ROC. Valid
values are: The $${P}_{D}=\frac{1}{2}\text{erfc}({\text{erfc}}^{1}(2{P}_{FA})\sqrt{\chi})$$ where For details about the other supported signal types, see [1]. Default: 

Detection probabilities corresponding to the falsealarm probabilities.
