Abstract
A time domain communications system wherein a broadband of time-spaced signals, essentially monocycle-like signals, are derived from applying stepped-in-amplitude signals to a broadband antenna, in this case, a reverse bicone antenna. When received, the thus transmitted signals are multiplied by a D.C. replica of each transmitted signal, and thereafter, they are, successively, short time and long time integrated to achieve detection.
Claims25
A method for indicating presence of an object through a structural wall, comprising:
- transmitting at least one wideband energy burst, said at least one wideband energy burst having a bandwidth sufficient to resolve said object, said at least one wideband energy burst reflecting off said object and producing at least one return signal;
- and
- receiving said at least one return signal to indicate presence of said object, at least one of said transmitting of said at least one wideband energy burst or said receiving of said at least one return signal being through said structural wall.
A method for indicating presence of an object through a physical barrier, comprising:
- transmitting at least one wideband energy burst, said at least one wideband energy burst having a bandwidth sufficient to resolve said object, said at least one wideband energy burst reflecting off said object and producing at least one return signal;
- receiving said at least one return signal to indicate presence of said object, at least one of said transmitting of said at least one wideband energy burst or said receiving of said at least one return signal being through said physical barrier;
- and
- filtering said received at least one return signal to sense velocity of movement of said object.
A radar system for indicating presence of an object through a structural wall, comprising:
- at least one transmitter for transmitting at least one wideband energy burst, said at least one wideband energy burst having a bandwidth sufficient to resolve said object, said at least one wideband energy burst reflecting off said object and producing at least one return signal;
- and
- at least one receiver for receiving said at least one return signal to indicate presence of said object, at least one of said transmitting of said at least one wideband energy burst or said receiving of said at least one return signal being through said structural wall.
A radar system for indicating presence of an object through a physical barrier, comprising:
- at least one transmitter for transmitting at least one wideband energy burst, said at least one wideband energy burst having a bandwidth sufficient to resolve said object, said at least one wideband energy burst reflecting off said object and producing at least one return signal;
- at least one receiver for receiving said at least one return signal to indicate presence of said object, at least one of said transmitting of said at least one wideband energy burst or said receiving of said at least one return signal being through said physical barrier;
- and
- a filter for filtering said received at least one return signal to sense velocity of movement of said object.
