\begin{abstract}
The advantages of the laser-guided bomb (LGB) as an air-to-ground
precision-guided weapon are high hit rate, great power, and simplicity
of usage. LGB is guided by semi-active laser ground-seeking, therefore
the impact of the atmosphere can affect how well it hits its target.
LGB's spatial release region (SRR) is challenging to calculate
precisely, especially with poor field of view, resulting in a lower real
hit probability. To increase the hit probability of LGB in tough
atmospheric situations, a novel method for calculating the SRR is
proposed. This method is based on the transmittance model of the 1.06 \selectlanguage{greek}μ\selectlanguage{english}m
laser in the atmospheric species and the laser diffuse reflection model
of the target surface to determine the capture target time of the laser
seeker. And then calculate the boundary ballistic space starting
position by ballistic model, and get the spatial scope of the spatial
release region. This method may determine the release region of
laser-guided bombs based on flight test data such as instantaneous
velocity, altitude, off-axis angle, and atmospheric visibility. The SRR
calculation method helped us improve the 9.2\% hit probability of LGB by
more effectively employing aircraft release conditions, atmospheric
visibility, and other factors.%
