The invention discloses a frequency domain data lossy compression method. The method comprises the steps of acquiring and grouping radio frequency domain data, converting the frequency domain data belonging to the same group into a frequency domain data matrix, converting each level sampling value of the frequency domain data matrix, dividing the matrix into sub-matrixes with the same size, performing dimension transformation on each sub-matrix, performing quantization processing, converting each obtained quantization matrix into a one-dimensional vector, conducting splicing to obtain a complete data coding vector, and constructing a compression result file in combination with frequency domain data information. Through a lossy compression mode, the compression ratio of the radio frequencydomain data is improved, and the radio frequency domain data can be utilized more efficiently and reasonably. 本发明公开了一种频域数据有损压缩方法，首先获取无线电频域数据并进行分组，将同属一组的频域数据转化为频域数据矩阵，然后将频域数据矩阵的各个电平采样值进行转化，然后分割成相同大小的子矩阵，对每个子矩阵进行维度变换，然后进行量化处理，将
