Beschreibung
Zusammenfassung:	The invention discloses an arbitrary trajectory cooperative detection imaging resolution characterization method based on a fuzzy function. The method comprises the following steps: constructing an arbitrary trajectory cooperative detection synthetic aperture radar imaging geometric model, and constructing a target plane geometric model; obtaining echo signals after range-direction matched filtering in an arbitrary trajectory cooperative detection synthetic aperture radar slant range course and a two-dimensional time domain; constructing a synthetic aperture radar generalized ambiguity function according to the echo signal after the range direction matched filtering in the arbitrary trajectory cooperative detection synthetic aperture radar slant range course and the two-dimensional time domain; obtaining a normalized synthetic aperture radar generalized fuzzy function; according to the range-direction resolution information, range-direction resolution is obtained; obtaining the azimuth resolution according to
