A radar subsystem within a radar system has a transmitter circuit for transmitting pulse modulated waves on a multiplicity of frequencies. A duplexer is electrically connected to the output of the transmitter circuit. A receiver circuit is coupled to the duplexer for receiving the pulse modulated waves of the multiplicity of frequencies while transmitting on said multiplicity of frequencies, except such frequencies being received at the same time intervals as the frequencies being transmitted.

Simultaneous transmit and receive radar subsystem

A radar system embodies a subsystem having an amplitude and phase modulator circuit, an amplitude and phase demodulator circuit electrically connected to and feeding the modulator circuit, and a pulse generator electrically connected to and feeding the demodulator circuit. A single traveling wave tube is utilized in the transmitting portion of the subsystem.
