The paper deals with the problem of the detection and the estimation of parameters of radar signals in the Gaussian white noise from the point of view of the theory of statistical decision. The design principle of the optimum radar receiver for signals of unknown parameters is given according to the characteristics of the high-speed target at distance and to the purposes of radar systems. Unified detection procedures are established the construction and the performances of the optimum radar receivers are obtained.The block diagrams of these results are also shown.Emphasis is given to the case where the prior distributions are unknown, while only two parameters, velocity and distance, are discussed for the case where the prior distributions "re known. For the latter case, the optimum estimations of these two parameters and their properties are derived from the absolute loss criterion.

This paper describes a laser velocity interferometer which can measure the velocity of high speed objects and get the velocity-time curves directly. Principles of the new laser interferometer and the results of our experiments are presented. The device is used to measure the velocity history of a bullet during its acceleration along the gun barrel. A 2 mW He-Ne laser is used for illuminating a scotch tape on the tip of the moving specimen giving reasonably good signal-to-noise ratios. The interferometer can...

This paper describes a laser velocity interferometer which can measure the velocity of high speed objects and get the velocity-time curves directly. Principles of the new laser interferometer and the results of our experiments are presented. The device is used to measure the velocity history of a bullet during its acceleration along the gun barrel. A 2 mW He-Ne laser is used for illuminating a scotch tape on the tip of the moving specimen giving reasonably good signal-to-noise ratios. The interferometer can measure the motion of diffusely reflecting surface, so it is insensitive to the tilting of specimen surfaces during the experiment. Thus the interferometer is believed to be very useful in high speed measurements.
