Introduction to Technical Seminar on Blue Eyes Technology:

The ability of the first generation RADARS are limited to detect only the object and they cannot sense the speed of the object.  From which we can only measure the echo on the screen and it don’t provide us much accuracy.

The intensity of the sound means the frequency of the sound waves seems to change when either the source or the observer are in relative motion. This wat we called as Doppler’s effect.

First the signal is sent from the unit to the moving object and then it receives the one which get reflects back. The speed of the object is obtained by comparing the signal sent and the one which we received.

Anti-radars: i) jamming device ii) detectors. Jamming Devices – SHF oscillators help in transmitting the signals to the speed cameras and collapse the measurement. Besides that the RADAR can detect these jamming signals and signal the police about this. A detector as a simple SHF receiver. These contain a microwave detector and alarm.

RADAR is not affected by rain or any other weather condition. Mist doesn’t have any relative motion with respect to radar and so there no affect in the measurement. The range of the RADAR to sense the speed of the object depends on i) the power of SHF oscillators’ ii) sensitivity of the detector. Power is low in oscillators and which are used in radars. The main problem in the Detector is signaling to noise ratio. RADAR works when a object nears it.

When several objects are moving at several speeds encounter at the RADAR shows the resulting Doppler signal consist of a mixture of signals at various frequencies. Presently the device gets collapsed and determines it as faulty. But now there are systems like DSP, to measure the speed of several objects simultaneously.
