Abstract (en)

[origin: US4673934A] Improved radar reflector apparatus of the type comprising a collapsible and inflatable envelope surrounding a collapsible reflector array made of reflectors which, when the envelope is inflated, form a plurality of corner reflectors. The improvement resides primarily in the fact that each of the reflectors is mounted or suspended in the envelope by a string mounting network independently of the others.
