Embodiment Construction
[0058] The present invention mainly uses the simulation experiment method to verify the feasibility of the system model, and all steps and conclusions are verified correctly on VC++ and MATLAB7.0. The specific implementation steps are as follows:
[0059] Step 1. Construction of the line array transmitter
[0060] The linear array transmitter on the launch platform of the dual station dual linear array 3D synthetic aperture radar system includes the following parts: a transmitter, a control switch, 1000 feeders and 1000 linear array feeders. Its system block diagram is attached figure 1 As shown, the control switch is connected to the receiver, the control switch is connected to 1000 line array feeders through 1000 feeders, and the length of the line array is 30. Within a flight aperture, the control switch controls the positions of the feeds that are turned on for each slow time n, n=1...2048, and only one feed is turned on for each slow time n. Each linear array feeder ma...
