Radar Information from the Partial Derivatives of the Echo Signal Phase from a Point Scatterer
Abstract
This report is concerned with the target information from a point scatterer as obtained from the partial derivatives of the echo-signal phase as a function of frequency, time, and spatial position. These partial derivates provide the three basic radar measurements of range, range rate, and angle. The angle rate found from the spatial doppler-frequency shift (due to a scatterer with a component of velocity perpendicular to the radar line of sight) is suggested as a fourth basic radar measurement. The direct measurement of angle- rate from the spatial doppler frequency is illustrated by the example of a scanning interferometer radar with a cosine radiation pattern. The relationship between the partial phase-derivative measurements and the more conventional radar measurements is shown.
