Abstract
A system for locating microwave radiation sources such as radar, jamming equipment and the like, employs a cannon launched shell including a frequency scanning receiver for the microwave emissions. Received information is processed on the shell and can derive signals that are used to modulate a telemetry transmitter. A ground base telemetry receiver associated with the launching cannon, includes means for processing the signals to derive the location of the microwave sources relative to the shell, and for processing information relating to the shell launch to determine its instantaneous position and attitude. The location of the sources relative to the launch site is then calculated and is used to aim the cannon and destroy the emission site.
Claims16
A system for detecting the location of a source of radio signal emission comprising an artillery shell containing a radio receiver for receiving radio signals from said source, means for processing the received signals and for producing position signals which are a function of the position of the source relative to the position of the shell, and a radio transmitter for transmitting radio signals containing data which includes the position of the source relative to the shell;
- a cannon for launching the artillery shell;
- a ground based receiver for receiving the artillery shell's radio signals;
- and a computer operative to receive said data from the ground based receiver and signals relating to the cannon operation, and operative to generate signals corresponding to the location of said emission source relative to said cannon.
In a system for locating sources of radio signals including a cannon and a computer operative to calculate the instantaneous position and attitude of shells launched by the cannon, a shell adapted to be launched by the cannon including sensor means for receiving the radio signals from the sources, a radio receiver connected to the sensor means, processor means for receiving the output of the radio receiver for generating signals including information relative to the location and identity of the radio signal sources, and a radio transmitter operative to receive the signals from the procesor and to modulate a transmitted carrier with said signals.
The method of detecting sources of radio signals comprising:
- launching a missile in a predetermined path in the general vicinity of the sources;
- receiving radio signals from the sources at the missile;
- generating position signals within the missile which are a function of the position of the missile relative to the sources;
- transmitting said position signals from the missile to a ground based receiver;
- calculating the instantaneous position and attitude of the missile and the location of the radio signal sources relative to the missile using the position signals, and calculating the position of the radio signal sources relative to the launch point.
