RADAR CHARACTERISTICS
The radar has been designed to have a specific set of functional characteristics which make it suitable for range
& speed measurements of multiple targets.
RADAR ANTENNA
The antenna design is a planar patch array with the following performance;
OPERATING FREQUENCY BAND AND POWER
The transmitter is interlocked as a closed loop system with the hardware processor. This enables full monitoring
of the transmitter frequency which ensures the transmission remains in the intended transmission band. The
design confidence means that the nominal centre frequency of the transmission shall remain within a 10MHz
window for the required 7 years for a radar functioning normally.
The change in frequency with temperature is measured to be <140KHz/˚C
The radar frequency and power is as follows;
