| 摘要 |
Techniques, systems and apparatus are described for a multimode passive detection system (MMPDS). A MMPDS includes a detector assembly of array of drift tubes arranged as detector modules to generate detector signal data representing electrical responses to cosmic ray charged particles passing through respective detector modules and traversing through a volume of interest (VOI). Detector circuitry measures the generated detector signal data and outputs the measured detector signal data as spatially segregated data streams corresponding to respective detector modules. A clock system distributes a master clock signal throughout the detector circuitry. A compute cluster including nodes of computing devices merges the spatially segregated data streams into temporally segregated data, obtains information on tracks of the cosmic ray charged particles based on the temporally segregated data, reconstructs an image of the volume of interest based on the obtained information, and identifies an object in the VOI based on the reconstructed image. |
