Home|IVS-947 – FMCW / FSK Radarsensor

Radar Sensor


Product family: VCO Radar Transceiver
Applications: Velocity Measurement, Vehicle Counting, Speed Enforcement, Traffic Applications, Industrial Applications
Functions: Movement, Velocity, Direction, Presence, Distance
The IVS-947 offers accurate motion detection for mid-range traffic applications. It is a VCO Transceiver, which enables the customer to switch between CW (continuous wave), FSK (frequency shift keying) and FMCW (frequency modulated continuous wave) mode. This enables the customer to extract information on velocity, direction of moving objects as well as it detects the presence and measures constantly the distance to stationary and moving objects. The K-Band sensor detects vehicles, typically up to 80m (depending on the radar cross section).
InnoSenT uses the latest MMIC technology in this product to achieve the best noise performance. It is also equipped with a RF Low Noise Amplifier and an IF Amplifier to improve the Signal-to-Noise Ratio. The product features a dual channel Receiver (I/Q channels) to differentiate the motion direction. The power consumption of the IVS-947 is reduced to enable energy efficient operation. The device can be operated worldwide. The design includes an RF prescaler to readback the current transmit frequency to stabilize CW signals or linearize frequency ramps. The 24 GHz Radar Front End is designed for speed measurement and vehicle counting, but can also be operated in industrial applications, where a larger field of view is necessary.
