Patent ID: 8446311

Claim:
A radar detection device comprising: a base n to which is allocated a nominal frequency Fn and a frequency band of width B′, on which are located pulsed Doppler UHF radars, of high repetition frequency Fr, each radar operating in a frequency band B, centred on an emission frequency Fi; wherein, each radar i utilizing a Doppler spectral band b 0 around its emission frequency Fi, the number N of radars that the base can comprise and the emission frequency Fi of each radar i are defined in such a way that the gap (F i −F n ) is smaller in absolute value than the difference (Fr−b 0 )/2 and is not a sub-multiple of Fr/2; a global Doppler spectral band b 1 corresponding to a maximum span of speeds being defined, the gap between the emission frequencies Fi and Fj of any two radars i and j of the base is greater than (b 1 +b 0 )/2.
