Improvement in Target Detectability Using Spread Spectrum Radar in Dispersive Channel Condition

摘要

With the advent of digital technologies, the pseudo LFM digital radar using polyphase code is gaining popularity as compared to once popular Analog LFM Radar. Benefits include improved target detection and avoidance of channel impairments by exploiting the higher processing gain of Polyphase codes. In this paper attempt has been made towards realizing such high performance spread spectrum radar. Latest equipments including AWG, VSG, and VSA are used for the realization. By eliminating channel impairments, the detectability of the target is extended towards target imaging which would lead to target classification.
