description	The invention discloses an arbitrary trajectory collaborative detection resolution analysis method based on vector gradient. The method comprises the following steps: obtaining an instantaneous slant range history gradient vector according to a slant range history of collaborative bistatic SAR imaging; constructing a distance resolution theory model based on the instantaneous slant range history gradient vector, and inversely solving the distance resolution theory to obtain the distance resolution; doppler frequency is obtained based on cooperative detection of a double-base forward-looking SAR signal phase; obtaining a Doppler frequency gradient vector based on the Doppler frequency; constructing an azimuth resolution theoretical model based on the Doppler frequency gradient vector, and inversely solving the azimuth resolution theoretical model to obtain azimuth resolution; and based on the included angle between the range resolution and the azimuth resolution, obtaining an actually measured range resolution
