Abstract
A multiple radar interference suppressor for use in a missile scoring system. The multiple radar interference suppressor phase locks the pulse repetition frequency of each drone (unmanned) aircraft to one other drone of the plurality of aircrafts. The phase of the pulse repetition frequency of each of the transmitting radars of the drones is slightly offset from one another. As a result, mutual interference among the drones transmitting radar signals and receiving radar signals of other drones is overcome. Lastly, the transmitted signals and received signals are encoded so that unwanted reflections and scattering from a target may be substantially eliminated or suppressed.
Claims20
A multiple radar interference suppressor comprising:
- a plurality of sources of radar transmit signals, said radar transmit signals having approximately the same frequency;
- means for receiving said radar transmit signals, said means for receiving coupled to said plurality of sources of radar transmit signals;
- means for phase locking a pulse repetition frequency of said received radar transmit signals of a first of said plurality of sources to a second of said plurality of said sources, said means for phase locking coupled to said means for receiving;
- and
- means for phase offsetting the pulse repetition frequency of said locked, received radar transmit signals of said first and second sources, said means for phase offsetting coupled between said means for receiving and said means for phase locking.
A missile scoring system for determining the affect of a fired missile on a plurality of drone aircraft (drone), said missile scoring system comprising:
- each of said plurality of drones including a source of radar transmit signals, each said radar transmit signal having approximately the same frequency as other signals of said drones;
- each of said plurality of drones including:
- means for receiving said radar transmit signals, said means for receiving coupled to said plurality of sources of radar transmit signals;
- means for phase locking a pulse repetition frequency of said received radar transmit signals of said one drone to another of said plurality of drones, said means for phase locking coupled to said means for receiving;
- means for phase offsetting the pulse repetition frequency of said locked, received radar transmit signals of said one and another of said drones, said means for phase offsetting coupled between said means for receiving and said means for phase locking;
- and
- means for transmitting a slope of said received radar transmit signals to an earth station for subsequent scoring analysis.
