A system for multistage aerial dispersion of materials or substances in minute form to provide an aerial array of interspaced clouds or cloud-like patterns of such materials or substances. Although the materials or substances may be in the nature of fertilizers, pesticides, herbicides and the like, suitable for domestic applications, there is basically disclosed a system for military applications. In this latter regard, rapid multipositional aerial dispersion of decoy material, such as thin metallic strips, chaff, or the like, to deceive or confuse enemy radar is achieved by packaging the decoy material in a carrier missile structured to carry a plurality of separate frangible canisters or modules respectively containing the decoy material in the form of a myriad of such metallic strips or chaff. The carrier missile while airborne is adapted to explosively shatter the canisters or modules in predetermined, timed sequence and thereby widely scatter their contents of metallic strips, or chaff, as a multitude of discrete dipolar elements to form a series of separate interspaced clouds or cloud-like regions of decoy material with each possessing the electronic or radar tracking characteristics simulating an airborne object, such as a helicopter or the like, desired to be protected from detection. Thus, the series of clouds or regions of decoy material conceal the actual locational position of the airborne object desired to be protected by producing multiple confusing tracking signals to devices relying upon such signals for detection and/or aiming purposes and thereby affording delay time to permit the real, or actual, airborne target to advance out of range of accurate detection and/or enemy weaponfire.
