Building off decades of testing and simulation in the field, Calspan has developed and continues to maintain expertise in radar signature analysis & modeling. Our expertise features determining target configuration (size, shape, mass, mass distribution), midcourse target dynamics (roll and precession periods, precession cone angle, wobble), deployment phase parameters (release times, spin up times, target orientation, throw weight), and reentry phase (ballistic coefficient, maneuvers, wake onset, stability parameter).

• Metric data analysis including trajectory reconstruction of powered flight parameters (acceleration, burn time), ballistic coefficients and target maneuvers
• Signature data analysis including sample interleaving analysis & coherent processing
• Radar performance evaluation (bias estimation and propagation)
• Radar signature modeling including geometric diffraction theory, direct radar signature synthesis, ground clutter
