The goal of pulse compression is to transmit a long duration pulse of high energy, but to detect a short duration pulse in order to localize the receive filter output response to one or at most two radar range bins. Early radars accomplished this by transmitting a signal with linear frequency...

τ = pulse width in seconds, fp = pulse repetition frequency in hertz. With the above, the form of the radar equation suitable for calculating the range is (Eq. 4)Rmax=[PavG2λ2σnEi(n)(4π)3kT0Fn(Bτ)fp(S/N)1Ls]1/4 The radar system losses Ls (number greater than one) have...
A large “pulse-compression gain” must be included somewhere in the equation if that bandwidth is used in the denominator. Similar confusion applies when digital Doppler filtering is used with a coherent pulse train, or when multiple pulses are integrated after envelope detection. Experience shows ...

The physical dimension of resolution cell can be easily calculated using equation given for range and angular resolution given above...
