Laplace transform.

A mathematical relationship to model a continuous function in the complex frequency domain (S-plane); Laplace transforms are commonly used by systems engineers to describe avionics systems; Compare: continuous-time equation, difference equation, differential equation, discrete-time equation, state-space model, Z transform; See Also: first-order filter, integrator, second-order filter, unit functions; Laser obstacle avoidance / terrain avoidance sensor (OA/TA). A sensor that provides warnings for long, thin objects (like wires). It has at least a 20deg x 30deg FOV, which is both velocity tracked and pitch stabilized. It provides warnings (every 2.5 seconds) for long, thin obstacles (like wires) at 400 meters detection range and contour flight at 80-120 knots.
