Simulating Quantum Radar with Brownian Processes

We present a set of stochastic differential equations, defined through Brownian processes, that are solved in the complex field. The corresponding Kolmogorov-Chapman equation of such processes is a Schrödinger-like equation and then, we can represent quantum noise corresponding to a specific system by solving stochastic differential equations through ordinary numerical algorithms, making their implementation easier. These numerical algorithms can be considered as a definition of the corresponding processes used to define them. An application to basic quantum radar is attempted with the scope to outline the calculation of ROC (Receiver Operating Characteristic).
