Device for warning of radar traps

Abstract

The invention relates to a device for warning of radar traps or speed radar signals, comprising a radar detection antenna, a central processing unit, which is connected to the radar detection antenna, an alert device or unit, which is connected to the central processing unit and which is designed for delivering an alarm, wherein the central processing unit is designed for determining at least one characteristic of the signal received by the radar detection antenna and for causing the alert device to deliver an alarm or suppress the delivery of an alarm in dependence on least one determined characteristic.

         2 . A radar detector for alerting a user of a speed radar signal, the device comprising:
 a radar detection antenna unit, wherein the antenna unit is enabled to receive at least one speed radar signal;   a memory unit, wherein the memory unit stores at least one known radar signal characteristic;   an alert unit for alerting the user of the presence of a speed radar signal; and   a central processing unit, coupled with the memory unit, the alarm unit and connected to the antenna unit, wherein the central processing unit compares the at least one signal characteristic of the at least one speed radar signal received by the antenna unit with the at least one known radar signal characteristic stored in memory; and suppresses the delivery of an alarm activation signal when there is a signal characteristic match; and   further comprising a signal profile threshold value database containing at least one signal profile threshold value wherein a signal profile value of a received signal is determined and compared to at least one threshold value by the central processing unit and depending on the comparison controls the alarm unit.
