rocpfa
Receiver operating characteristic curves by false-alarm probability
Syntax
[Pd,SNR]
= rocpfa(Pfa)
[Pd,SNR]
= rocpfa(Pfa,Name,Value)
rocpfa(...)
Description
[
returns the single-pulse
detection probabilities, Pd
,SNR
]
= rocpfa(Pfa
)Pd
, and required SNR
values, SNR
, for the false-alarm probabilities
in the row or column vector Pfa
. By default,
for each false-alarm 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.
[
returns
detection probabilities and SNR values with additional options specified
by one or more Pd

Input Arguments
|
False-alarm probabilities in a row or column vector. |
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.

This property specifies the type of received signal or, equivalently,
the probability density functions (PDF) used to compute the ROC. Valid
values are: The where For details about the other supported signal types, see [1]. Default: |
Output Arguments
|
Detection probabilities corresponding to the false-alarm probabilities.
For each false-alarm probability in |

Signal-to-noise ratios in a column vector. By default, the SNR
values are 101 equally spaced values between 0 and 20. To change the
range of SNR values, use the optional |
