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 <64KHz/˚C
The radar frequency and power is as follows;
*Proposed channels for FCC variant, channel 1 - 24.099GHz, channel 2 - 24.148GHz.
FREQUENCY MODULATION
The radar is an FMCW radar where the Frequency Modulation (FM) characteristics give the radar a transmit
bandwidth of 44MHz. The FM is such that it is symmetric about the centre frequency of the band it is operating in.
The change in transmit ‘bandwidth’ with temperature is measured to be typically 30KHz/˚C. The stability of the
bandwidth over time is anticipated being better than 3% in the first year and lower for each subsequent year.

OVERVIEW
Available as simple single opto output or as dual opto output with added functionality.
POWER & CONNECTIONS - 12VDC/24VAC/DC - SINGLE OPTO OUTPUT
12Vdc/24Vac/dc - Bulgin connector or 5m flying lead
The output is an SPCO (SPDT) Opto with the impedance state of the relay being the same for a detect state or
power o condition. Connection is via a Bulgin Buccaneer 9-pin connector as below and on page 7 with pins 7, 8
and 9 not connected.
Upon power up, owing to the nature of the equipment’s power supply, an initial current of up to 200mA can be
drawn and the supply should be fused appropriately. The installation of this equipment must conform to the
latest edition of the IEE Wiring Regulations (BS7671).
The voltage tolerances of supply are as follows:
dc : 10.8-29V
ac : 18-30V
The nominal current is 225mA at 12Vdc and 160mA at 24Vdc.
