Given $3$ pulses, what is the required single pulse SNR needed to achieve an overall probability of false alarm of $\backslash (10^\{-5\}\backslash )$ and overall detection probability of $0\mathrm{.}95$ for the following cases:

$1)$ Coherent integration,

$2)$ Non$-$coherent integration,

$3)2$ of $3$ Detection Scheme.
