The present invention provides a radar detector comprising: an antenna connected to a signal receiver; a first mixer to mix a signal from a first heterodyne antenna and an antenna signal; an amplifier; a second mixer to mix a signal from at least one second heterodyne with the amplified signal; a bandpass filter; a signature module; and a central processor to output information on radars detected by an audio amplifier and a dynamic, wherein the central processor controls the at least one heterodyne and the one first heterodyne (using a saw-tooth voltage generator connected thereto). Moreover, this radar detector includes a photodiode and a connected laser module, and a signal from the module is analyzed by the central processor. The present invention is capable of improving the sensitivity and interference immunity. |
