Because if they didn't use frequency modulation it wouldn't be called an "FM" CW Radar...
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
" FM " is.
AM - Amplitude Modulation FM - Frequency Modulation
FM means frequency modulation AM means amplitude modulation
Amplitude Modulation (AM) Frequency Modulation (FM)
am is amplitude modulation, fm, frequency modulation
The modulation index formula in frequency modulation (FM) is given by the equation: β = Δf / fm, where β is the modulation index, Δf is the peak frequency deviation, and fm is the modulating frequency. Modulation index indicates how much the carrier frequency is being varied by the modulating signal in FM.
AM = Amplitude Modulation. FM = Frequency Modulation

A: FM means frequency Modulation meaning the frequency remain the same. pulse modulation the frequency can vary
AM stands for amplitude modulation FM stands for frequency modulation
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
