The invention provides a linear array SAR (synthetic aperture radar) imaging algorithm based on compressed sensing. Aiming at the characteristic that the scattering targets are sparse in an actual linear array SAR three-dimensional scene space, the method comprises the following steps of: only selecting less linear array antenna array elements to work in stead of adopting full array elements to receive an echoed signal; performing two-dimensional compression on the distance direction and along-track direction of the linear array SAR echoed data by utilizing a matched filtering technology; establishing a linear measuring matrix of a cross track direction signal and a sparse target scattering coefficient by adopting a compressed sensing technology; and finally, reconfiguring a cross track direction target through solving an optimization problem to realize sparse target imaging processing in a three-dimensional space. By using the method, the defect of the existing linear array SAR matched filtering imaging algorithm can be overcome, the linear array antenna array element quantity and system data acquiring and storage burden are greatly reduced, and the cross track direction imaging precision of the linear array SAR is improved.
