ION-FAST 2022-2023 dataset

IONFAST_V_PNG_AUG2022.zip - archive of vertical sounding ionograms in PNG format, registered with ION-FAST during test operation at the Vasilsursk test site in August 2022. IONFAST_V_NPZ_AUG2022.zip - Archive of vertical sounding ionograms in NPZ format (Numpy python zip archive), registered with ION-FAST during test operation at the Vasilsursk test site in August 2022. Each NPZ file contains three variables: "f_axe" - frequency axis (one-dimensional array); "h_axe" - height axis; "ion" - ionogram (two-dimensional array). ION-FAST_FW_V_TX_BPSK.bit - Red Pitaya SDRlab 122-16 firmware that implements the ION-FAST's (vertical ionosonde) TX part with BPSK manipulation. ION-FAST_FW_V_RX.bit - Red Pitaya SDRlab 122-16 firmware that implements the ION-FAST's (vertical ionosonde) RX part. ION-FAST_FW_V_RX.c - the source code of the program that writes the stream of samples from the FPGA to the memory card of the SDRlab 122-16 board. ion-fast-sw.zip - archive with source code, executable file (for the arm6 architecture of the SDRlab 122-16 board) and example input data for the program for calculating the averaged ionogram from a stream of IQ samples. ION-FAST_Chirp_Cyprus_tests.zip - archive containing: 1) files with IQ samples of ION-FAST (chirp ionosonde mode) recordings made on 04/15/2023 11:05:20 UT, 11:20:20 UT and 11:35:20 UT ("bin" extension); 2) files with IQ samples of records made at the same time by a commercial ionosonde ("wav" extension); 3) jupyter notebook file containing the script that calculates and plots ION-FAST's oblique sounding ionograms.IONFAST_V_PNG_AUG2022.zip：2022年8月于瓦西里苏尔斯克（Vasilsursk）试验场开展测试运行期间，由ION-FAST登记备案的PNG格式垂直测高电离图归档文件。 IONFAST_V_NPZ_AUG2022.zip：2022年8月于瓦西里苏尔斯克试验场开展测试运行期间，由ION-FAST登记备案的NPZ格式垂直测高电离图归档文件（NPZ为Python Numpy压缩归档格式）。每个NPZ文件包含三个变量："f_axe"——频率轴（一维数组）；"h_axe"——高度轴；"ion"——电离图（二维数组）。 ION-FAST_FW_V_TX_BPSK.bit：适配Red Pitaya SDRlab 122-16的固件程序，实现ION-FAST（垂直电离探测仪）的发射（TX）模块，采用二进制相移键控（Binary Phase Shift Keying，BPSK）调制方式。 ION-FAST_FW_V_RX.bit：适配Red Pitaya SDRlab 122-16的固件程序，实现ION-FAST（垂直电离探测仪）的接收（RX）模块。 ION-FAST_FW_V_RX.c：用于将现场可编程门阵列（Field-Programmable Gate Array，FPGA）采样流写入SDRlab 122-16板载存储卡的程序源代码。 ion-fast-sw.zip：包含源代码、可执行文件（适用于SDRlab 122-16板的arm6架构）以及用于从同相正交采样（In-phase and Quadrature sampling，IQ采样）流计算平均电离图的程序示例输入数据的归档文件。 ION-FAST_Chirp_Cyprus_tests.zip：包含以下内容的归档文件： 1) 2023年4月15日世界协调时（Universal Time，UT）11:05:20、11:20:20及11:35:20采集的ION-FAST（线性调频电离探测模式）IQ采样记录文件（扩展名为.bin）； 2) 同期由商用电离探测仪采集的IQ采样记录文件（扩展名为.wav）； 3) 包含计算并绘制ION-FAST斜测电离图脚本的Jupyter Notebook文件。
