Dynamic Threshold Calculation for Millimeter Wave Radar Based on Environmental Noise
To effectively eliminate invalid targets and reduce the probability of false alarms, a dynamic threshold calculation method based on radar ambient noise statistics and target power distribution characteristics is proposed. The histogram statistical method is used to estimate the noise level of each range gate and search the peak value to find the local peak point. Simultaneously, the adaptive peak detection threshold is obtained by dynamically allocating the threshold gain according to the attenuation of different range gate radar signals. The local peak point is then taken as the signal of the reference unit and input into the detection method to solve the detection threshold. The experimental results show that the proposed method can effectively identify radar targets in complex application scenarios.
