For improving the SNR and the reducing transmit power of the SAR simultaneously, airborne SAR often use high PRF (Pulse Repetition Frequency).
机载SAR为提高信噪比并同时减少发射功率,往往使用较高的脉冲重复频率(PRF)。
参考来源 - SAR实时并行成象系统研究Under the same conditions, doubling the pulse width or pulse repetition frequency, the jamming results were similar. Because the pulse shortening effection was relatively difficult currently, increasing the pulse repetition frequency was more feasible.
但是由于脉冲缩短效应还是当前面临的技术难点,所以通过发展开关技术以提高重复频率是更可行的办法。
