Data Visualization for Low-Frequency Inverse Synthetic Aperture Radar (ISAR)

Methodology

As shown in Figure 1, the low frequency ISAR project starts off with a transmitter that converts data into step-frequency pulses and transmits. This radar is made up of four major block diagrams. 1) Xilinx Development board is a programmable board that sends out the pulse; 2) FPGA (Field-Programmable Gate Array) Extension board has the annexes which allow the signal to be transmitted through the antennas; 3) Data Acquisition board which collects the received data and sends it to the FPGA board; 4) The FPGA board analyzes the data and allows it to be seen on the computer, through the Matlab code that was built for the radar. The radar also has an IF mixer which allows the reference signal and the received data to be synchronized, combined and sent to the data acquisition board.
