Digital radar system and method.

摘要

A digital radar system (10) digitally encodes inputs and outputs associated with radar signals. Digital radar system (10) comprises bandpass filter (22), analog-to-digital converter (26), and digital beamforming processor (36). Fiber optics manifold (30) distributes signals within digital radar system (10). Digital beam steering processor and synchronizer (40) processes and generates synchronizing signals. Transmitter/receiver modules (14) synthesize independent radar signals and communicate radar signals to digital radar system (10). Preselection and preamplifying circuitry (20) preselects and preamplifies a certain aspect of the radar signals. Hilbert transform (28) communicates with converter (26) to transform digital signals to digital complex sample signals. Baseband transform filter (32) transforms digital complex sample signals to baseband complex sample signals. Low pass filter (34) filters and communicates filtered sample signals to beamforming processor (36). <IMAGE>
