Frame Generator

A frame consists of a certain number(N) of chirps and timing parameters between frames.

1. Timing Parameter

The frame cycle is composed of the preparation period T_PRE, a sequence of N Chirps, and the idle interval T_NOP.

T_PRE serves as the initial setup time for the system, while T_NOP acts as the final guard interval before the subsequent frame begins.

Since T_NOP allows the system to enter idle mode, the total operating current can be controlled by adjusting this duration.

2. Frame Rate and Duty Ratio

The frame rate determines the data update speed, which is critical for tracking fast-moving targets and minimizing detection latency.

Meanwhile, the duty ratio defines the system’s power consumption
