[0035] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] The present invention discloses a radar automatic gain method, device, equipment and storage medium based on color block analysis, aiming to solve the problem that the existing gain adjustment method is not flexible enough when facing different targets and environmental conditions, resulting in excessively strong or weak signals, thereby affecting the detection capability and accuracy of the radar.

[0037] See also Figure 1 The first embodiment of the present invention provides a radar automatic gain method based on color block analysis, which can be executed by a radar automatic gain device based on color block analysis (hereinafter referred to as a gain device), and in particular, executed by one or more processors in the gain device to at least implement the following steps:

[0038] S101, receiving a radar echo signal, scanning the echo signal and saving the scanned data points;

[0039] In this embodiment, the gain device can be a terminal with data processing capabilities such as a server, workstation, desktop computer, notebook computer, tablet computer, single-chip microcomputer, etc., which can establish a communication connection with the radar to control the radar system to transmit signals and receive echo signals. The gain device can be installed with a corresponding operating system and application software;

[0040] Specifically, in this embodiment, the radar system first transmits a signal and receives an echo signal reflected from the target. The gain device uses a high-speed analog-to-digital converter (ADC) to convert the received analog signal into a digital signal. After completing the analog-to-digital conversion, all data points obtained in each scan will be stored in the signal receiving module. Each scan consists of N scan lines, and each scan line contains M data points. In order to accurately represent the intensity of each data point, a P-bit binary number is used for encoding in this embodiment, where N, M, and P are all fixed constants.

[0041] S102, assigning the data points scanned in the entire circle to five different color disk categories, and generating an assignment result, wherein the color disk categories include overflow signal, strong signal, medium signal, weak signal and noise;

[0042] In this embodiment, after each scanning cycle is completed, all the acquired data points are classified. Specifically, the gain device assigns these data points to five different color disk categories, which respectively represent overflow signal, strong signal, medium signal, weak signal and noise.

[0043] The overflow signal category is used to identify data points that exceed the dynamic range of the radar system. These signals are usually too strong and may cause the system's analog-to-digital converter (ADC) to saturate. Identifying these data points as overflow signals can effectively avoid signal distortion caused by over-enhancement during the gain adjustment process, thereby protecting the system's performance.

[0044] The Strong Signal category includes those signals that are strong but within the acceptable range for the system. The Medium Signal category includes data points with moderate strength, and the Weak Signal category identifies those signals that are close to the system noise floor, which may include echoes from distant targets or weak reflections. Finally, the Noise category includes data points with strengths below the Weak Signal threshold, which are essentially devoid of any useful information, but whose presence and quantity are critical in assessing the system noise level.

[0045] S103, generating a detection condition based on the allocation result, increasing the gain based on the initial step on the initial gain value until a detection condition of excessive gain is triggered, halving the initial step and reducing the gain until the detection condition of excessive gain is not triggered, halving the current step again and increasing the gain;

[0046] S104, repeating the gain value adjustment process until the step reaches a preset value or a detection condition where the gain is too small, and outputting a final gain value.

[0047] It should be noted that the color disk categories include: Category a: equal to MaxValue, representing overflow signal. Category b: greater than or equal to HighThreshold, representing strong signal. Category c: greater than or equal to MediumThreshold, representing medium signal. Category d: greater than or equal to LowThreshold, representing weak signal. Category e: less than LowThreshold, representing noise. Among them, MaxValue, HighThreshold, MediumThreshold, LowThreshold, and LowThreshold are fixed constants.

[0048] In this embodiment, the radar system generates detection conditions in the gain adjustment process by analyzing the color disk category of the scan result. Specifically, the system first sets the initial gain value based on the allocation result, and starts gain adjustment in combination with the initial step value. The gain adjustment is performed step by step, and the system increases the gain value in each adjustment until the detection condition of excessive gain is triggered. When excessive gain is detected, it indicates that the radar system may have signal saturation or the system exceeds its dynamic range, so the system halves the initial step value and begins to gradually reduce the gain until the system no longer triggers the detection condition of excessive gain.

[0049] During this process, the setting of detection conditions is extremely crucial. Detection conditions for excessive gain include that the number of overflow signals is greater than the sum of the numbers of strong signals and medium signals, or the sum of the numbers of overflow signals and strong signals is greater than the sum of the numbers of medium signals, weak signals, and noises, or the number of weak signals is greater than the number of noises (if a > (b + c), it indicates excessive gain and the signal intensity exceeds the ADC sampling range; if (a + b) > (c + d + e), it indicates excessive gain and the image is overly saturated; if d > e, it means the background noise is raised to level d). The setting of these conditions can ensure that the system will not cause signal oversaturation during the gain adjustment process, thus maintaining the detection accuracy and signal integrity of the radar system.

[0050] Subsequently, during the process of reducing the gain, the system halves the current step again and continues to increase the gain value, repeating this process. This is repeated until the step value reaches the preset value or the detection condition for insufficient gain is triggered. Detection conditions for insufficient gain include that the number of medium signals is less than the number of strong signals, and the number of noises is greater than the sum of the numbers of strong signals, medium signals, weak signals, and noises (that is, if b < c, it indicates insufficient gain as the number of medium signals is less than that of strong signals; if e > (a + b + c + d), it represents excessive noise ratio and insufficient gain). The system can prevent the gain adjustment from being overly reduced and ensure sufficient detection ability when processing weaker signals.

[0051] When the system completes all adjustments and the step decreases to the preset value or the detection condition for insufficient gain is triggered, the system will output the current final gain value. Through this dynamic and precise gain adjustment method, the radar system can adapt to signal intensity changes under different environmental conditions, significantly improve the detection accuracy and stability of the system, and ensure high-performance signal processing ability under complex and changeable conditions. This gain adjustment mechanism not only effectively reduces the false detection rate of the system but also improves the adaptability and robustness of the radar system in various environments.
