Device for Warning of Radar Traps

摘要

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.

主权项

1. 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;
wherein the at least one known radar signal characteristic is comprised of at least one of: the structure of the amplitude of the signal over a predetermined distance; the modulation frequency of an amplitude modulation on the signal; the modulation depth of an amplitude modulation on the signal; the modulation frequency of a frequency modulation on the signal; the frequency sweep of a frequency modulation on the signal; the phase of a phase modulation on the signal; the modulation frequency of a phase modulation on the signal; the duty cycle of a pulse modulation on the signal; the modulation frequency of a pulse modulation on the signal; the frequency stability of the signal; or the phase noise of the signal; 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.
