Measurements of monostatic target strength are often made in the near field of the target. This memorandum investigates some model-based inversion techniques which can be used to predict far field monostatic target strengths as a function of aspect angle from the near field measurements. Simulated and experimental data are used to illustrate the accuracy of the proposed methods.
