The Korean Microlensing Telescope Network ( KMTNet ) will consist of three 1.6m telescopes each with a 4 deg ^ { 2 } field of view ( FoV ) and will be dedicated to monitoring the Galactic Bulge to detect exoplanets via gravitational microlensing .
KMTNet ’ s combination of aperture size , FoV , cadence , and longitudinal coverage will provide a unique opportunity to probe exoplanet demographics in an unbiased way .
Here we present simulations that optimize the observing strategy for , and predict the planetary yields of , KMTNet .
We find preferences for four target fields located in the central Bulge and an exposure time of { t _ { exp } } = 120 s , leading to the detection of \sim 2,200 microlensing events per year .
We estimate the planet detection rates for planets with mass and separation across the ranges 0.1 \leq M _ { p } / \mathrm { M } _ { \earth } \leq 1000 and 0.4 \leq a / { AU } \leq 16 , respectively .
Normalizing these rates to the cool-planet mass function of Cassan et al .
( 21 ) , we predict KMTNet will be approximately uniformly sensitive to planets with mass 5 \leq { M _ { p } / { M } _ { \earth } } \leq 1000 and will detect \sim 20 planets per year per dex in mass across that range .
For lower-mass planets with mass 0.1 \leq { M _ { p } / { M } _ { \earth } } < 5 , we predict KMTNet will detect \sim 10 planets per year .
We also compute the yields KMTNet will obtain for free-floating planets ( FFPs ) and predict KMTNet will detect \sim 1 Earth-mass FFP per year , assuming an underlying population of one such planet per star in the Galaxy .
Lastly , we investigate the dependence of these detection rates on the number of observatories , the photometric precision limit , and optimistic assumptions regarding seeing , throughput , and flux measurement uncertainties .
