Abstract：With the requirement of high resolution and wide swath, multiple-transit and multiple-receive SAR becomes a important research field, multiple apertures use the same carrier wave frequency, transit orthogonal phase coding signal is one of modes, which can be implemented in the engineering . Through the particular research of the echo array and the echo phase compensate four kinds’ impossible methods of echo processing and the signal matrixes of the methods are proposed. The simulation with orthogonal chaotic coding signal shows the effectiveness of the methods.
