Nonlinear Trajectory Generation for Unmanned Air Vehicles with Multiple Radars 
Abstract 
The problem of finding a real time optimal … The problem of finding a real time optimal
trajectory to minimize the probability of detection (to maximize
the probability of notbeingdetected, pnd, function) of
unmanned air vehicles by opponent radar detection systems
is investigated. This paper extends our preliminary results
on low observable trajectory generation in three ways. First,
trajectory planning in the presence of detection by multiple
radar systems, rather than single radar systems, is considered.
Second, an overall probability of detection function is
developed for the multiple radar case. In previous work, both
probability of detection by a single radar and signature were
developed in the theory section, but the examples used only
signature constraints. In this work, the use of the overall
probability of detection function is used, both because it
aids in the extension to multiple radar systems and because
it is a more direct measure of the desirable optimization
criteria. The third extension is the use of updated signature
and probability of detection models. The new models have a
greater number of sharp gradients than the previous models,
with low detectability regions for both a cone shaped areas
centered around the nose as in the previous paper, as well as a
coneshaped area centered around rear of the air vehicle. The
Nonlinear Trajectory Generation method (NTG), developed
at Caltech, is used and motivated by the ability to provide
real time solutions for constrained nonlinear optimization
problems. Numerical simulations of multiple radar scenarios
illustrate UAV trajectories optimized for both detectability and
time. optimized for both detectability and
time. +
