Abstract : The results of coherence measurements of three free precession proton magnetometers are discussed. The measuring and data processing instrumentation is described. The noise associated with the instrumentation has been measured and presented in statistical form. The results of measurements with elementary local perturbations are included to illustrate the target detection problem. The limitations of the instrument for target detection are discussed and improvements suggested. (Author)
