Passive radar for terminal area surveillance: Performance feasibility study

Future Direction □ This work represents an initial look █ Designed for a first-pass at the possible merits of PBR for the NAS █ Rough airspace model and notional receiver █ Results are not final: Should guide further evaluations □ Unresolved Questions & Future Work █ Used ITM 50% propagation — refine temporal variability █ Update the airspace model to be more-specific to each airport █ Refine the simulation to describe the receiver required to achieve defined performance metrics, rather than the fractional performance provided by a fixed receiver █ Consider gap-filling by additional illuminators (e.g., spacecraft)
