COMPARITIVE ANALYSIS BETWEEN SZ PHASE CODING AND BATCH MODE MITIGATIVE RANGE AMBIGUITY
摘要
Abstract
Range ambiguity is an inherent problem of the pulse Doppler weather radar. For X band radars whose wavelength is shorter, the ambiguity is particularly serious. At the beginning, the principles of two mitigative range ambiguity algorithms, batch and SZ phase coding, are presented. Then comparison is done with their clutter suppression capability, applicable elevation, scan time, and algorithm complexity etc. Moreover, according to their actually sampled X band radar echo signal, the effect of their mitigative range ambiguities are compared. Then conclusion is drawn that the effects of SZ phase coding is obviously superior to batch since despite of its more sophisticated calculation, it not only satisfies the real-time processing requirement but also is free to all elevations.关键词
