| Abstract: | The Target Echo Signal Simulator(TESS) for interferometric SAR was designed and implemented.The TESS can make a hardware-in-loop simulation loop with radar working in interferometric bistatic mode.It recorded the transmitting signal of the master satellite in real-time,supplemented the scene modulation information off-line,and played back the radar echo of master and slave satellite according to the radar PRF.The high digital IF transmitting and receiving technique was used to achieve better harmonic,clutte... |
