Abstract. In this paper the impact of SAR raw data compression on the interferometry height accuracy was researched. The performance measures of SAR data compression were introduced. Models of data compression/decompression were created. The performances of BAQ algorithm, BAQ algorithm in data polar format, vector quantization algorithm, wavelet transform D4 algorithm were researched. The estimation of SAR interferometry height accuracy was obtained.

Key words: SAR data compression, BAQ, vector quantization, Daubechies wavelet D4, SAR interferometry.
