Project 2 — B-21 Standoff Emitter Geolocation#

Group projectDue Lesson 2040% deliverable category

Background#

In Block 2 you learned to listen: a radar warning receiver hears a threat emitter and measures its angle of arrival (L13), and crossing bearings from different points locates the emitter (L14). This project turns that skill into an operational product. A B-21 on a standoff orbit can hear the radars of an integrated air-defense system long before it must enter their lethal range. Each RWR bearing is a line of position; cross several of them, taken from different points along the aircraft’s path, and the lines intersect at a fix. The precision of that fix — not merely its existence — is what decides whether the location is good enough to cue a weapon. Your group is the B-21 mission-planning cell: a strike package needs weapon-quality locations for the emitters defending a target area so a standoff weapon can be cued onto them. You must design a passive collection — where the B-21 flies and how it gathers bearings — that geolocates those emitters precisely enough to cue the weapon (\(\mathrm{CEP} \le 0.5\) km for the lethal emitters), while keeping the aircraft outside every threat’s engagement range. Accuracy wants you close and moving; survivability wants you far. That tension is the project.

IADS_Scenario.csv — emitter priors and keep-out radii

The MATLAB collection simulator rwr_collection_sim.m and the starter code/L19_Project2Starter.m are bundled in the course code download with the scenario CSV beside them — the starter flies a sample leg, collects noisy bearings, and cross-fixes one emitter with its error ellipse so your group starts at the geometry, not the plumbing. The true emitter positions are hidden inside the simulator; estimating them is the task.
