A platform for SAR imaging is designed in our company. ADC raw data is captured and the SAR imaging is implemented.
As so far, the near field SAR imaging is developed.
Here we can show some results. left-up image shows the radar sensor, left-down image shows the scene of two corner reflectors, and the right image is the SAR.
We did some real scene test with our developed RMA SAR Imaging.
From the SAR image, we can see that the rear part of the car is clearly imaged. The left wall of the parking place echoes strong reflection. The ceiling beam above the car has also focused image at the distance of 6m downrange.
This algorithm is developed and tested for near field SAR imaging, which is very challenged for automotive short range radar.
The results will be published in the IEEE Radar conference in 2023.
Good luck.
This is 77Ghz TI radar, the next work around is to generate SAR image by using cascaded solution for near field applications like parking.
