Sidelobe Suppression (SS) can be found on almost every Linear Frequency Modulated (LFM) pulse radar receiver|Shift-Frequency Jamming (SFJ) is an important method to realize deception jamming using the inherent coupling property between time-delay and frequency-shift of this LFM signal. So, the inter-ambiguity function (IAF) of LFM with SS using normalized parameters including time-delay rate and shift-frequency rate is analyzed. Then the 3:1 cone than weighted, Hamming weighted and cosine square weighted are focused and some parameters related to detection are analyzed. Compared with the none SS, the weighted shift-frequency signal to Jamming loss and the weighted shift-frequency jamming to noise loss are present like M function having the max shift-frequency rate point equal to ±0.29. And the impact of weighted shift-frequency pulse-width loss are decide by none shift-frequency.
