雷达有效目标生命周期算法c++代码

由于有效目标的定义和生命周期的计算方式不明确，以下是一个可能的实现，仅供参考。

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define MAX_TARGETS 100
#define MAX_LIFETIME 10

typedef struct {
    int id;
    int start_time;
    int end_time;
} Target;

int main() {
    Target targets[MAX_TARGETS];
    int num_targets = 0;
    int current_time = 0;

    // 随机生成目标
    srand(time(NULL));
    for (int i = 0; i < MAX_TARGETS; i++) {
        if (rand() % 2 == 0) {
            targets[num_targets].id = i + 1;
            targets[num_targets].start_time = rand() % MAX_LIFETIME;
            targets[num_targets].end_time = targets[num_targets].start_time + rand() % (MAX_LIFETIME - targets[num_targets].start_time);
            num_targets++;
        }
    }

    // 模拟雷达扫描
    while (current_time < MAX_LIFETIME) {
        int num_detected = 0;
        int detected_ids[MAX_TARGETS];

        // 扫描
        for (int i = 0; i < num_targets; i++) {
            if (targets[i].start_time <= current_time && targets[i].end_time > current_time) {
                detected_ids[num_detected] = targets[i].id;
                num_detected++;
            }
        }

        // 输出扫描结果
        printf("At time %d, radar detected %d targets:", current_time, num_detected);
        for (int i = 0; i < num_detected; i++) {
            printf(" %d", detected_ids[i]);
        }
        printf("\n");

        // 更新时间
        current_time++;
    }

    // 计算有效目标生命周期
    for (int i = 0; i < num_targets; i++) {
        int lifetime = targets[i].end_time - targets[i].start_time;
        printf("Target %d's lifetime is %d\n", targets[i].id, lifetime);
    }

    return 0;
}
