Current release is version: 13
Release Date | Version | Description |
Aug. 2016 | 1 | Design with 32K FFT. |
Sept. 2016 | 2 | Bug fixes on Version 1. |
Sept. 2016 | 3 | Bug fixes on Version 2. |
Sept. 2016 | 4 | Made blanking output signal active low. Bug fixes in sweep blanking. |
Jul. 2017 | 5 | Debug version for issue observed in lab by Navtech. Frames appear to be offset in memory and possibly some frames are lost. |
Jul. 2017 | 6 | Debug version for issue observed in lab by Navtech. Frames appear to be offset in memory and possibly some frames are lost. |
Jul. 2017 | 7 | Latest debug version delivered to Navtech. Includes new register for alarms. Issue with address offset observed by Navtech was resolved without RTL modification (modified SW programming sequence). |
Sept. 2017 | 8 | Check-in for V0x08. Modified low precision dB data to be generated from 42 or 47 bit linear power data. Added control bits for selecting truncation mode for linear power data. |
Jan. 2018 | 9 | Amended the active_fft_bins_octates register function to create a window for DMA transfer of the FFT bits. |
May-22 | A = V10 | Attempted bug fix for fixing radar image rotation issue due to variations in radar's angular speed. |
May-22 | B = V11 | Attempted bug fix for fixing radar image rotation issue due to variations in radar's angular speed. Applied modifications on Version 7, since Versions 8 and 9 were not adopted by Navtech. |
May-22 | C = V12 | Attempted bug fix for fixing radar image rotation issue due to variations in radar's angular speed. |
Jun. 2022 | D = V13 | Attempted bug fix for fixing radar image rotation issue due to variations in radar's angular speed. Introduced register-controlled cut-off threshold for disabling sweep triggering when the radar is overspeeding. |
Jun. 2022 | E = V14 | Final modification of solution given in Section D. This has solved the issue. |
