Abstract
Methods and systems are provided for controlling a radar system of a vehicle. In particular a method and apparatus are taught for a predictive tracking algorithm for predicting the power of a target cluster for the next frame and determining a predicted cluster power for the next frame. The updated power of the next cluster frame is a function of the predicted power, the current measured power and the SNR of the environment. The power of cluster is computed taking into account the energy backscattered by each detection inside the cluster.

A method comprising:
- transmitting a first radar signal;
- receiving a reflection of the first radar signal;
- detecting a first cluster in response to the reflection of the first radar signal;
- determine a first cluster power in response to the first cluster;
- transmit a second radar signal;
- receive a reflection of the second radar signal;
- detecting a second cluster in response to the reflection of the second radar signal;
- determine a second cluster power in response to the second cluster;
- compute an updated cluster power in response to the first cluster power and the second cluster power;
- and
- tracking the second cluster in response to the updated cluster power.
An apparatus comprising:
- A transmitter for transmitting a first radar signal and a second radar signal;
- A receiver for receiving a reflection of the first radar signal and a reflection of the second radar signal;
- A detector for detecting a first cluster in response to the reflection of the first radar signal and a second cluster in response to the reflection of the second radar signal;
- A processor for determine a first cluster power in response to the first cluster, a second cluster power in response to the second cluster, the processor further operative to compute an updated cluster power in response to the first cluster power and the second cluster power;
