Laboratory work needs not only accurate measurements but also correct calculation.
Moreover, they do not allow accurate measurements of either the temperature or the intensity and direction of the E- field in proximity to the samples.
A surveying technique in which a region is divided into a series of triangular elements based on a line of known length so that accurate measurements of distances and directions may be made by the application of trigonometry.
An accurate replica of the source should be provided for practice in handling and for making accurate measurements of source-detector distances.
A method of accurate measurement of the range,azimuth and elevation of a target is developed under the background of strong interference for sparse array synthetic impulse and aperture radar (SIAR). Computer simulation results show this method is effective.
