Mathematical models are developed to describe the capability of human operators observing A, B, and PPI displays of noncoherent radars for detecting target signals in receiver noise. The models are derived from visibility data of World-War II experiments using curve-fitting techniques guided by simple physical models. The trends of performance are compatible with the predictions of detection theory, but calibration constants are assigned based upon experimentally determined human operator characteristics. Radar variables which are incorporated in the models include pulse length, receiver bandwidths, antenna beamwidth and scan rate, pulse repetition frequency, and display brightness, geometry and phosphor characteristics. Data are presented from experiments on detection of target signals in sea clutter by human operators.
