Today i acquired what i think is the first SAR image using the audio input on a laptop to digitize raw de-chirped radar data and transmit synchronization pulses.
This was done as part of preparation for Monday's lecture on SAR imaging for the MIT IAP course, 'Build a Small Radar System Capable of Sensing Range, Doppler and Synthetic Aperture Radar Imaging.'
A photo of the radar used to acquire this SAR image is shown. This radar is made out of coffee cans, a block of wood, a few mini-circuits parts, solderless breadboard, runs on 8 AA batteries, and uses your laptop's audio input port for digitization. Data is recorded as a .wav file then processed in MATLAB.
Complete details on this will be posted to the MIT Opencourseware site later this winter.
Can you let us know when the details will be posted? For example, with blog posting at the time?
