Abstract:

Coherent detection on a pulsed radar is discussed from a statistical decision theory viewpoint. The Neyman Pearson test is applied to two cases first, where it is desired to detect targets moving with one particular radial velocity, and second, where it is desired to detect targets at all velocities equally well. In the first case it is shown that, in a sense an ideal integrator is achieved i.e., the results are exactly the same as if all the power reflected from the target were received in one pulse, rather than many. A mechanization for the second case is given. The statistics for a suboptimum integrator which approximates the Neyman Pearson test in a simpler form are derived. The performance of this integrator is compared with that for the ideal noncoherent integrator.
