pytorch_3dfft's Introduction

PyTorch 3DFFT

针对 TDM MIMO FMCW 雷达,3D-FFT 的 PyTorch 实现。可作为网络层放入到任意网络中。

处理过程

RangeFFT -> DopplerFFT -> cfar(可选) -> PhaseCompensation -> AngleFFT

输入维度应为 [batch, tx, rx, chirp, sample]。即,按照 batch、天线、慢时间维度、快时间维度进行排序。

输出维度为 [batch, angle, doppler, range]

使用方法

安装

将本项目 clone 到本地,使用 pip install -e . 安装。

代码示例

准备好雷达输入,维度应为 [batch, tx, rx, chirp, sample]

实例化网络:

from pytorch_3dfft import RadarData
from pytorch_3dfft.utils.CFAR import CFAR_OSCA_2D

cfar = CFAR_OSCA_2D(3, (40, 20), 1e-9)
pre_process = RadarData((2, 4, 255, 128), (128, 128, 128), cfar_module=cfar)

其中,cfar 是继承于 nn.Module 用于 CFAR 处理的网络层。(2, 4, 255, 128) 指定了输入维度,(64, 256, 128) 指定了输出维度。
