This paper presents a method and implementation on Blind Method with Digital Frequency Diversity in receiver for pulse radar. First of all, in order to solve the problem of near-blind-field of detection range, we propose a blind method of double-pulse which including wide pulse and narrow pulse. Then, we complete the frequency separation of dual-frequency and double-pulse in one channel of the receiver, which not only eliminate the effect of near-blind-field, but also breaks through the inherent way that we must copy receiver channel under the traditional blinding method. Finally, we got the performance tests results which verified that the effectiveness and practicability of this method.
